Aluminum Slotted Top Rail

This round aluminum slotted top rail, also called a glass railing top cap, glass cap rail or glass handrail cap, finishes the top of a glass railing. It is extruded from 6063-T6 aluminum with a U-channel built inside the round tube. The top edge of the glass panel slides into the slot from below, and a rubber glazing gasket holds it tight. The result is a clean, continuous round top rail with no visible clamps or fasteners. Available in 2" (1.900" OD) and 2½" (2.500" OD), and cut to your exact length at our Everett, WA shop.
