Repeatable Stair Layout
Clamp the pair to the rise and run marks on a framing or Speed® Square. Set once, trace every tread and riser down the stringer board without remeasuring between steps.
Solid Brass Body
Machined from solid brass for a non-marring grip on the square’s edge. Steel gauges can scratch anodized aluminum; brass conforms to the edge instead.
Precision-Machined Faces
Contact faces seat flush against the square’s edge for true 90° clamp-up. A skewed gauge throws the stair pitch off by half a degree on every tread.

A closer look
Two matched brass clamps in the kit. Position one at the rise mark and the other at the run on the square’s edge, then trace every stair cut from the same two stops.
Both gauges ship on one card. A stair pitch needs two stops, the rise and the run, so one card stocks the kit without mixing single-unit SKUs.
