Cutting finish treads to fit an existing masonry stair

Stairs

Cut Lists

Cladding an existing stair means every finish tread is cut to a step that was poured or laid, not built to a drawing, so the widths wander and the nosings are never quite where the last one was. The T1R Range reads each step and drops the figure into the calculator in the app, so the allowance comes off the measured step rather than being carried in your head between the stair and the saw.

A masonry stair under construction is measured step by step, the treads rough and the risers open. A rugged tablet showing a calculator keypad sits on the steps alongside, and readings are taken along each tread in turn. A finished step with a fitted tread is shown at the end.
