Compact Aluminum Measurement Aid

Precision Stair Gauge & Square Assist Clamp
Stop fighting with your tape measure and square. This compact aluminum jig locks onto your carpenter's square to provide a stable, perpendicular reference point for perfect 90-degree cuts every time. Ideal for stair stringers, framing, and repetitive layout work.
Perfectly Perpendicular Every Time
Manual layout often leads to drift and inaccurate cuts. By clamping this gauge directly onto the edge of your speed square or framing square, you create a rigid fence that stays true. The tall body design ensures your tool remains fully perpendicular to the wood surface, giving you confidence in every mark.
- Stable Reference: Eliminates hand wobble when marking lines.
- Repeatable Results: Set it once and glide across multiple boards for identical measurements.

Built for Job Site Durability
Crafted from CNC-machined 6061 aluminum, these gauges are lightweight yet incredibly tough. The anodized finish resists rust and wear, ensuring they look new even after months of use in sawdust and moisture. The knurled thumb screw allows for tight lockingāeven when wearing thick work glovesākeeping your ruler firmly in place during operation.

Works With Your Favorite Tools
You don't need to buy a new set of rulers. These auxiliary clamps are designed to fit most standard carpenter squares, including Speed Squares, Rafter Squares, and Framing Squares. They act as a universal adapter, turning any straightedge into a reliable guide for circular saws or pencil marking.
