Using your original glass, you can reglaze and restore the waterproof seal between glass and aluminum sash.
This gray vinyl rubber strip is designed for 2mm glass (3/32″) inserted in an aluminum channel approximtaely 17/32″ deep and 7/32″ wide. Thicker glass may work with this gasket because there are rubber spacer fins on the sides.
Remember that rubber stretches somewhat so measurements are approximate when installed.
Sold in 48-foot packages.
