Screen clips for single pane Concourse windows (Hehr 4700 Series, single pane, circa 1997-98-99))

Post by Blue~Go »

Hi all,

This discussion was started in another thread (will come back and post link), but since that thread was originally about some completely different windows, and since I have an update, I figured I'd start a new thread to make it easier to find (thread title will show up in search, is obvious).

The windows this topic applies to are the single pane Concourse windows used (just) prior to when they went to double pane, which I think was around 2000. I'm pretty sure I have heard of this style on at least 1997, 1998, and 1999 Concourses; not sure if they would apply to other years or to Premier windows.

On this window style, the screen does not ride in its own track, like is often the case. Instead, it rides on the inner rim of the main track (that the opening window pane rides in). Nothing holds it in place except for small plastic clips. No clips, no screen stay in - it just falls out and you have a screen/frame in your hand (or on the floor...)

When I got my rig, the sink side window had a full complement of clips (six, although seven might be even better). So I could see how it should be. The stove side screen was (sort of) held in by mounds of tape. I found one precious clip on the floor behind the club chair. I then carried this clip around for two years, stopping in to every new/old/dusty RV place I could find. No-one knew a thing about it. I also scoured the web (Google, Pellandent, Interstate Metals, and on and on). No dice. I also called Aubrey's RV, and they seemed to know the clips I was referring to, but said they had never been able to get them, even though they had tried.

All this time, although I was looking at any and all clips, I thought the windows were SE-GI brand. That's because there was a SE-GI glass pamphlet in the big book of instruction manuals and the like that came with my Chinook. And for while I thought SE-GI was out of business. (Then VTSweetPea here set me straight). Here is what we are talking about:

So my next move (last week) was to call SE-GI. That was a bit frustrating, due to an impossible to get through phone system, so I emailed them. Lo and behold a fellow from the engineering department wrote back and was very interested in helping. So I made up some annotated photographs and drawings to show what they looked like and how they worked. He called me back and said that he had not recognized the clip/window, and that he had also taken the time to run it by people who had worked there in the late 1990's, plus also the owner. They didn't think it was a SE-GI window either. They suspected it was a Hehr window.

So we talked about what markings were on the glass. It's "Janel" glass. He said they did use Janel glass, but then so did other companies, such as Hehr. He said the true ID label would likely be on the inside of the flange, so only viewable if removing the whole window from the coach. Usually Hehr has a small red logo, but mine don't have that. He also said that in that era, Trail Wagons went back and forth between Hehr and SE-GI, so that might explain why the SE-GI brochure was in with my Chinook manuals by mistake. (SE-GI now makes their own glass, but at that time they were using Janel glass, like is in my windows). My windows also have "buttons" screwed into the top track to limit how far you can open the window. These buttons are listed as a Hehr part (I found later). SE-GI uses a piece of plastic laid in the lower track for the same function.

So even though it doesn't look like I have SE-GI windows, he was super helpful and has now sent me out some track pieces that, while clearly not the correct ones, might be modified to fit. What great customer (or in this case, not-even-a-customer) service! I don't have the clips yet, but they should arrive later this week.

Meanwhile, as soon as we got off the phone I did another search, this time concentrating on Hehr, and within two minutes had found my clips. DISCONTINUED! :x :x Parkin (who distribute Hehr stuff) has them on their website (second row on left), but have removed the part number and put the word discontinued there instead. Darnitall! I also then found threads with several other folks looking for them, all to no avail. The only slight success was that someone found a few in an RV salvage yard, but they were brittle/broken.

http://www.parkin-acc.com/page52.html

There is another Hehr clip that on first glance looks similar (and is still made), but actually the flanges go the wrong way, so not useful looking.

I will contact Hehr though just to see. Maybe they do have some old dusty ones, or if nothing else, maybe a drawing that could aid in 3D printing some new ones.

In the meantime, I took inspiration from RetiredTim here, and the fellow at SE-GI, and tried making my own. I don't have much with me for that type of raw materials, but I cut up a fat drinking straw and managed to make some that do at least hold the screen in place as I sit here in camp. Cross ventilation!!!! I don't think they will stand up to either driving or sliding the screen, but it's a start. They are definitely not putting any stress or distortion on the screen, which I worried that something like hose might, although maybe it doesn't (that's what RetiredTim used). Thanks to Tim for the idea of making something - having seen the real clips, which have a thin, complicated extrusion shape, I couldn't envision making something (maybe he never saw the real clips, so had a more open mind?).

I will keep folks posted, but wanted to start this thread now since we were all just talking about these.

If you have this style window screens/clips, it would be great if you could post your year and model of Chinook, so we can identify the range (my guess is 1997-1999 Concourse for sure, maybe 1996. Premiers?).

Here is a link to the previous thread, which was actually started about a completely different style of windows (in a 1994 Concourse) but morphed into talking about the screen clips:

Interesting. I posted about them likely being Hehr windows in the other thread and also the Parkin link. Since you were convinced that they were SEGI I dropped it and didn't follow up that I also talked to Hehr who forwarded me to Parkin (their largest parts reseller). I dropped it at that since I had no skin in the game, had already wasted 10 hours on the research, and your SEGI focus. Hopefully you will get more traction with Herh or Parkin. Best of luck and GET THOSE CLIPS ! :D

Yes, as it turns out you were right that they are Hehr windows. I was fooled because Chinook included a "SE-GI glass" brochure in the owners packet of documentation that came with my rig. Also there is no Hehr logo on the windows, which usually exists on Hehr windows (small red logo). So you could tell they were Hehrs somehow; but I couldn't. Apparently Chinook went back and forth from SE-GI to Hehr and back to SE-GI in that era, so that's likely why a "SE-GI glass" document was in with my Chinook owner's manual and appliance and feature documents. Just a mistake by Trail Wagons.

It sounds as if you may regret having tried to help; it was nice of you to try, and I'm sorry if you wish you hadn't, or feel that we didn't respond well. As I mentioned above, without the typical Hehr logo, and with a big, "SE-GI glass!" brochure in my Trail Wagons documentation, I couldn't help but think they were SE-GI. Even the woman at Aubrey's RV thought they were SE-GI (I'll have to call them back now just to make SURE they don't have any of the clips we need).

However, we all still can't just buy Hehr clips, because while the clips you referred to are still made (and sold by Parkin and others), they aren't the clips that fit these particular Hehr windows. They fit some other (presumably newer) style of Hehr windows. The shape of those goes up at the edges where it needs to go down for our windows. The clips that do fit these windows (pictured on the Parkin page I linked to, but marked as discontinued) have been discontinued by Hehr, and are no longer carried by Parkin (or anyone else that I can find).

I'm going to contact Hehr themselves, just in case they saved some in a back room, or can send me a drawing to possibly have 3D printed by someone else. However other folks on the Internet who also need them have not been successful, so it's a long shot. That has never stopped me from trying though!

In the meantime I took inspiration from RetiredTim and made a set out of a wide plastic drinking straw. Not as good as the originals (probably would fail if I slid screen open and closed, and may fail on bumpy road - haven't tried yet), but the screen is IN and I'm creekside, enjoying the laughing water sounds and *cross ventilation*. Finally! I never would have tried that if not for the combination of the ideas I got here, and the suggestions from the fellow at (ironically) SE-GI.

I also have some clips coming from the very helpful fellow at SE-GI, which while clearly not the correct ones, may be modifiable to fit, and work better than a cut up drinking straw :D

Thanks for contributing to both the other screen thread and this one.

I'll post back on what I do/don't find out from Hehr.

Just an update:

1) My screen is still holding in place just fine with the "drinking straw" clips. However, I can tell they would not hold up to sliding the screen open and closed this way. Maybe if the "clips" were adhered to the window (I just have them pressed in place for now). Also not sure about rough roads. But.... my window is open and I have cross ventilation and no bugs!

2) I wasn't able to get to the post office in time to pick up the possibly-modifiable SE-GI clips before the weekend, so that'll be tomorrow. I have a feeling that I may be able to modify them to work better than drinking straws :?

3) I exchanged a series of e-mails with Hehr last week. First supplying various photos and sketches of the windows (because even though I had the photo of the exact clip from Parkin's web site, this didn't allow them to know which "series" the windows were... for some reason). It's great that they are trying to help. At the end of the day Friday I got another e-mail back saying this:

That is a 4700 series window. And yes, it was obsoleted not long after yours was made. I don’t hold out much hope, but I am going to check around and see what I can find.

Well, now we know we have Hehr 4700 Series windows, for what it's worth. (Apparently not much these days :roll: the windows are in such great shape - as well they should be as 15 years is not a long lifespan for a window - that it's somewhat irksome they would make critical parts obsolete. I have Hehr windows in an early 1970's trailer that are still nearly as good as new, so come on!)

I'll update again with news of either how the SE-GI clips might work, or when I hear back again from Hehr.

So, knowing that these windows are "4700 Series" I did some more Googling. I found a place that shows 6' lengths are available. Sure, it's nearly $80 with the $36 shipping (gahhhh), but six feet would be enough to do five Concourse's worth of windows, so if it were the right part I'd likely order it and then we could share them around.

However, the drawing doesn't look anything like the actual clips, so I'm mildly skeptical. I'll be calling them tomorrow to inquire. Not going to just take a chance at that price.

I have also found possibilities on a few other sites, thanks to now knowing more about the windows. However they all add up ($$) and none of the photos or drawings look exactly right. I don't mind spending for the right clips; but don't feel like forking over $50-$100 and then something useless shows up. Therefore I will make some contacts tomorrow and report back.

PS: If anyone is missing any of the pull handles, they are available, known as a "pound on handle."

An update: I found two places on line that said they had the 4700 series screen clip. Both were expensive enough - and had enough "doubt factor" that I decided to contact and make sure they were the right part before ordering.

One was All-Rite. They had the right description (although it was a 6' length not 1" clips, but could easily be sliced), but the drawing didn't look right. It would have been ~$80 with shipping to get a length so not something I was just going to order on a lark. Well, I sent them photos of the correct clip and they said theirs was nothing like it. Sigh, scratch that one.

The second was State Trailer. The photograph looked like it could be the right one, but it was quite blurry and zoomed in was even worse. They also only had 11 clips between all their stores, but I figured that was still 11 more than we had now. I called and then sent photographs of my clips. They were very helpful but sadly, they said they are not even close. Not only are were not the right shape, but they were much tinier than ours. So not even a good candidate for modifying.

I still have Hehr checking, and am on my way to pick up the SE-GI clips from the post office today, so will update when I have more info.

What about creating a mold out of clay or something soft using an existing clip. Then fill the mold with something like Bondic or the like?

Possibly. The problem is the clips are *really* thin. Yesterday, I tried using and modifying several of the clips that SE-GI so kindly sent me, and although I could make several of them fit into the groove in the screen track, the issue became that the plastic (although quite thin) was not thin enough. I guess they can't be too rich or too thin :lol:

So I went back to my drinking straws for now :?

Still hunting and also open to ideas though!

Could you post pics of your straw system ?
Thanks

I like how you called it a "system." Kinda makes it sound official :mrgreen:

Anyway, first a bit more on the clip front: No word back from Hehr, and no luck finding the clips I had pictured earlier in the thread. But I did make one discovery. This came about because I had a full set of original clips on the sink-side screen, and no clips on the table side one. I used my straws on the table side. But, one weakness of the straws is they don't allow the screen to slide open as well (or for as long without breaking, I imagine). Well, I rarely have occassion to slide open the sink side screen, whereas I do like to open the table side one reasonably often to photograph birds or etc. that I see while sitting at the table sipping coffee of a morning.

So, I decided to switch the clips from the sink-side screen to the table side one, and then use the straw "system" ( :lol: ) on the sink side. That way I could slide the table side screen open on the original clips.

The first thing I noticed is that all the clips weren't the same. That was when I figured out that the bottom clips are different, and serve to "hold up" the screen (otherwise it tends to sink down) as well as somewhat holding it in place. Then the top clips mostly just hold it in place. So THEN I went hunting again, and found that I think the bottom clips ARE available (I am going to order some and will report back, as we've all seen how this sort of thing goes .... no counting chickens yet). I'll report back on this. But even if these are the correct ones and available, they won't work on the top (I tried) so something else is still needed in place of the top clips.

I did find that straws only around the full window tend to hold the screen frame up almost as well as the real bottom clips and also work decently well in place of the top clips. So to summarize, a full set of top and bottom original clips is the best. Original bottom clips combined with straws also works very well (bottom clips won't work on the top and the top clips are seemingly impossible to buy). But full straws (top and bottom) also works pretty well, considering -- even with no factory clips, albeit I don't think they'd stand up to repeated sliding of the screen open and closed.

Plus don't forget that there is RetiredTim's 1/4" hose method. I'm not sure if that might bend the screen frame (maybe Tim can answer this). Straws definitely don't.

So, I started with what you might call "smoothie straws." What makes them different from typical ones is they are a bit larger in diameter. These were about 7/16" (about 11mm) vs. a typical straw which I measured at just over 1/4" in diameter (about 6.5mm). Here is a photo that shows what I used (slightly thicker construction might be nice, but I'm camped in the boonies so only had what I had).
IMG_0199.jpg
I cut sections that were just a bit over an inch long (original clips were an inch, so just chose it somewhat arbitrarily, but easy enough to experiment on length). Then I used scissors to cut them lengthwise into a sort of long U shape (this one is already cut, which is why it looks smaller in diameter - it folds in on itself a bit).

Okay, on to the next post due to the photo limit....
