CRL's Premium Cap Rails are manufactured using precision Bump-Forming to deliver consistent radii, tighter tolerances, and reduced spring-back versus roll-formed rails. Welds on both sides of the internal channel increase strength and stability for fabrication, allowing rails to fit into welded corners without twist or discoloration—making this a top-performing bump-formed cap rail for glass railing projects.
All CRL Premium Cap Rails are formed with precision tooling for uniform diameters and smooth hairline transitions at splices, corners, and end caps. The welded internal channel improves structural integrity for on-site fabrication. Use Cat. No.
32629 Metal Contact Cement to achieve a secure, permanent bond at all connections. Use connector sleeves to join cap rails. Standard sale length: 120" (3.05 m); 168" (4.27 m) available.
Glass installation notes: When used with 1/2" (12 mm) glass, use Cat. No. GR5PV cap rail vinyl and
95CBL Silicone. For 5/8" (16 mm) glass, secure with 95CBL Silicone and shims. For 3/4" (19 mm) glass, use 95CBL Silicone and
shims. Contact
CRL Technical Sales for detailed installation guidance or a quote.
All CRL Premium Cap Rails are stainless alloy 304; stainless alloy 316 is available by special order. Use connector sleeves (search:
