Damaged glass door rails can be quickly and inexpensively replaced by using CRL Glass Door Replacement Rails. The aluminum rails are 15/16" (23.8 mm) in width and 5/16" (7.9 mm) in height at the top of the rail. You can install the rail with screws, rivets or sealants. We recommend either M66GRY or 777GRY as a sealant for the application. Sliding Screen Door Rails, Sill Track Cover, Threshold Replacement Kits and OEM Replacement Thresholds are also available.
