Installation Guide

Measure the width of your stair tread and cut the profile to length using a hacksaw or metal-cutting blade. Position the nosing at the leading edge of the step, ensuring the tread section sits flat and the riser drops down the front face. Secure with contact adhesive, epoxy adhesive, or countersunk screws through the pre-drilled fixing holes. Press or snap the coloured PVC insert into the channel until fully seated. Allow adhesive to cure fully before use.
