CRL's Premium Cap Rails (SKU: GR25BS6) are manufactured using a precise bump-forming process that delivers tighter tolerances, consistent radius, and superior fit compared with roll-formed cap rails. Welds on both sides of the internal channel add strength and stability, preventing twist, discoloration, spring-back, and stress common to roll-formed products—making these bump-formed premium cap rails ideal for architectural railing and glass guardrail applications where durability and a clean finish matter.
All CRL Premium Cap Rail components are formed with precision tooling to maintain uniform diameters for smooth hairline transitions at splices, corners, and end caps. The welded internal channel increases rigidity for fabrication. Use Cat. No.
32629 Metal Contact Cement to achieve a secure, permanent bond at all connections, and Connector Sleeves (
rail connect sleeve) to join cap rails. Sold in 120" (3.05 m) lengths; 168" available.
Glass securing recommendations: For 1/2" (12 mm) glass use Cat. No. GR5PV Cap Rail Vinyl and
95CBL Silicone. For 5/8" (16 mm) glass use 95CBL Silicone and shims. For 3/4" (19 mm) glass use 95CBL Silicone and
shims. Contact
