CRL-Blumcraft® Top Quality Extruded Cap Rails (SKU: 324MPK) are precision-extruded from 6063-T5 aluminum for long-lasting performance on glass shower doors, interior glass partitions, and balcony glazing. Designed for 1/2" (12 mm) glass, these cap rails are ready to install and provide a clean architectural finish. Choose from two architectural anodized finishes or mill aluminum from stock. Stainless steel adapter strips, very high bond cladding tape, and splice pins are required for a secure installation and are sold separately.

When using CRL-Blumcraft® 324 and 339 Series cap rails, install stainless steel adapter strips onto the glass edge with very high bond tape before fitting the cap rail. Each cap rail ships with pre-drilled mounting holes 24" (610 mm) on center and set screws along one side for proper attachment to the adapter strips.
