Identify make of window?

Hehr is the most common window but they have a clear Hehr code stamped on them. I think many campers of the era cut corners by making their own windows or using "no-name" windows from a small supplier. Hopefully somebody with more knowledge of Trotwood will chime in.

Okay, I found proof that it's a Philips.

SORRY NCCAMPER I RESPONDED TO THE WRONG POST, BUT THE MEASAGE IS THE SAME.


You're on the right track but asking the wrong question.  It really does not matter whom actually built or marketed your window frames.  No one is going to have the parts by brand.  What matters is that you obtain the various seals and gaskets in the correct sizes and materials that fit "Your Windows".  Every manufacturer made many changes to their window production making it very difficult to know what parts to order, that is if you can even find sources to order the parts.  It has been my experience that several sources that advertise gaskets and seals are simply re-selling generic window and sliding door seals that are commonly available at your local hardware stores.

The problem is in fit.  As you are now aware the seals slide into channels extruded into your aluminum frames.  Not only is the width of the seal mounting flange important, but the height of the seal.  Some of the seals you will need are "bubble seals" and others will be the frizzy wiper seals.  Save the old worn-out seals and make sure you know exactly what seal was used in each location.  Hint......always do one window at a time so you have a sample for referance.

Buy, or source a Metric Caliper to measure each seal in both directions.  IMO, it's easier to use the metric measurement when doing this fine size work.  It's simply easier to add and subtract numbers than to convert fractions.  All hardware stores, including your Big Box stores have a section for aluminum door and window parts.  Unfortunately, since there are no standard sizes, every store has different vendors and different size seals/gaskets.  If you go to two or three different hardware store chains, and a couple of different Big Box store chains you will most likely be able to find every size you need.

The message is.............you need to accurately measure the seals you need...............and take your measurements AND the caliper with you to the store so you can measure the seals before you buy a barn full that will not fit your needs.  Some of these calipers are sold as Vernier Calipers.  The newer are digital, but the old mechanical work just fine.  I bought my Dial Indicator Caliper broken more than twenty years ago and I use it daily.
