would anyone know where to get the little plastic drains that fit on the bottom of the windows? It looks like a cover of some type!!

I called Peninsula Glass in WA and gave them the description of the double pane windows. They no longer make our model. They will sell their current weep hole covers for a few bucks. When you get them you will find them 1/4" too long between the push pins. You carefully cut them in half and remove the 1/4" and then glue them together with Instant glue (Crazy Glue from Walmart). Hold them for ten seconds and they are done. Push them in place carefully and you are done. Ours are four months old now and still in place. You can do the same with any of the types sold in MH supply stores. Make the cut with a sharp, new single edge razor blade and be sure the ends are as perfectly aligned as possible.

no way I sealed 'em up!

The only time mine are "sealed" is when I haven't cleaned the bugs out recently. They seem to work well, never had water inside.

My coach has the cheaper Hehr windows, they have slots in the bottom channel for drainage. (I'm not sure they ever had covers.)

I just got a kick out of weep hole "covers" When I get another hunnert Barth projects done I'll get around to weep hole covers. (Seems like they would more likely plug and/or restrict drain flow anyway, defeating purpose of the weep holes?)

Not hootin' on Tom and Julie, I'm just a long way from that particular project!
