Window corner radius

[Cat futrell]

How can I determine the corner radius of my side window?

[Byron Kinnaman]

What I would do is first use a large compass, (drawing compass) and get an approximate measurement. Then draw radii in 1/4" or 1/2" increments on a piece of paper. Hole the paper up to see which one is the best fit. If don't have a good fit draw another radii between the two closest. Keep this up until you're satisfied with the results.

A starting point would be to measure across the corner where the curves end. That should be the diameter, 1/2 of that would be the approximate radius.

And why do you want to know the radius, buying new windows? Go to easyRVwindows.com, this is Atwoods site, they have a radius template that you can print. It is for 2.5" and 3" radius which they say is standard for most windows. If this doesn't work you can do like Byron says and make your own template.

I figured there should be a printable radius gauge someplace. Here's the link

I'm rebuilding rear side windows and wanted to check replacement prices. Wasn't sure what my radius was. Now I know, 3" - but after checking prices I will just keep on rebuilding - thanks all.

I could not find a replacement window that did not have outrageous prices except from Scamp. Their rear window fit our Uhaul with only a little modification to the opening. Scamps' side window was too small and I had to make an aluminum filler piece, and of course after all that work those NOS windows became available. A Scamp side window costs about $150, and they are available in either slider or crank out. I have the measurements if you want to try that route.
