CRL‑Blumcraft® Top Quality Extruded Cap Rails (SKU: 324SAPK) are engineered for glass balustrades and railing projects requiring a durable, architectural aluminum cap rail. Made from 6063‑T5 extruded aluminum, these cap rails provide a clean finished edge for 1/2" (12 mm) glass and are available in two architectural finishes plus mill aluminum for quick project matching.

Key differentiators: stainless steel adapter strips (sold separately) and very high bond cladding tape are required and recommended to secure the glass before installing the cap rail; cap rails include pre‑drilled holes 24" (610 mm) on center and set screws along one side for positive attachment to adapter strips. Available in 120" stock lengths or custom fabricated to your size for faster installation and consistent finish.

Installation tip: Apply stainless steel adapter strips to the glass edge with very high bond tape before sliding on the cap rail for a secure, professional result.
