This is oversized window gasket used on Spartan front/side plexiglass windows and picture windows on 1953-1955 Spartans. This is a little bigger than the original, but we have found that it works better. We do not recommend using this oversized gasket for the center window of 1947-1953 Spartans because the center window has an aluminum channel on the inside to hold the gasket, and this seal does not fit in the aluminum channel. The specs show this to be used with 1/32" to 1/16" panel and 3/16" to 1/4" glass but we use this with our reproduction polycarbonate windows which are .177" thick and it works fine. The glass and panel sit a little deeper in this gasket than the original sized gasket so it stays in the channel better. The distance between where the aluminum panel and the glass goes is 1/4". This is the gasket we recommend for all of the front side curved Spartan windows. Be sure to check your measurements carefully to be sure this will work on your application.
