This is the original type window gasket used on 1947-1953 Spartan front plexiglass windows and some windows in entry doors. The specs show this to be used with 1/32" to 1/16" panel and 13/64" to 1/4" glass but we use this with our reproduction polycarbonate windows which are .177" thick and it works fine. The distance between where the aluminum panel and the glass goes is 1/4". Be sure to check your measurements carefully to be sure this will work on your application.
Sold by the foot. The longest length we can get in one piece is 50 ft
*YOU WILL NEED THE LOCK STRIP TOOL TO INSTALL THE LOCKING STRIP FOR THIS SEAL. YOU CAN SEARCH FOR THIS TOOL UNDER THE PART #COT001.
