Tredsafe Rakeback Stair Edge Trim with PVC & Photoluminescent Insert

Improve stair-edge grip, visibility and protection with the ASL20 57 x 55mm Tredsafe Stair Nosing. Designed as a heavy-duty rakeback profile, it combines a robust aluminium body with a high-grip PVC insert for demanding domestic and commercial stair installations.

Part of the Tredsafe Aluminator® range, the profile incorporates a photoluminescent element that charges from natural or artificial light and glows in darkness. This helps define the stair edge during low-light conditions or power failure without requiring wiring, batteries or an electrical supply.
