CRL Extruded Aluminum Cap Rails are manufactured from alloy 6063‑T6 for strength and consistent profile—ideal for custom finishes such as anodizing or powder coating. Connector sleeves join cap rails for continuous runs; Cat. No. 32629 Metal Contact Cement is required to ensure a secure, permanent bond at all connections. These extruded cap rails are suited for glass balustrade and glass railing applications where finish options and field adaptability matter.

Glass fit and recommended inserts

• 1/2" (12 mm) glass: use Cat. No. GR5PV cap rail vinyl and 95CBL silicone
• 9/16" (13.52 mm) laminated glass: use Cat. No. LR56PV rubber insert and 95CBL silicone
• 5/8" (16 mm) glass: use 95CBL silicone and shims
