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. Available in 12, 25, 50 or 100 foot lengths.
