Greatest towing window idea

[Greg Gauper]

I use something similar, in that I use the rubber door stops to hold a plexiglass window in place, but then I secure the window with a 2"x1" strip of wood about 18-24" long. The wood rests on the window ledge on the inside and has a rabit on one edge that fits between the window and the ledge. I use thumb screws with large washers to go thru the window and into the wooden strip. The wooden strip has threaded inserts so I don't have to fumble around looking for nuts. Everything goes together by hand.

Basically the rubber door stops just hold everything in place until I can can secure the strip of wood. You could omit them, but then you need another set of hands to tighten everything up.
