Aluminium stair side trims are pre-formed angle profiles designed to finish the exposed sides of steps on open string staircases. Also commonly referred to as stair stringer trims or stairway side edging, they provide a clean, professional finish by concealing the edge of the floor covering and stair edging.
The trims are available in pre-formed angles of 90° for straight steps and 83° for rake back steps, ensuring an accurate fit to the staircase profile. Depending on the thickness of the floor covering, installation is assisted using the supplied PVC dual-height positioning tabs, allowing precise alignment with the finished floor surface.
It is recommended that stair side trims are installed before fitting the stair nosing and floor covering.
