This simple accessory expands the capabilities of a metal ruler by adding a reliable reference surface. It can also be mounted to a shop-made story stick for direct measurement transfer, and accepts 3/16" to 1/4" diameter round stock for use as a depth gauge. Combined with a 6" ruler, it even serves as an improvised double square.

Precisely machined from aircraft-grade aluminum, the 2 3/4" × 1" × 1/2" body presents a broad bearing surface for positive registration. To ensure a firm, square hold on even the thinnest rulers, the jaws have bevelled faces and travel on 1/4" dia. steel guide rods to prevent racking.

Maximum opening of 1 1/2". A convenient and well-made accessory for layout, repeat measurements, and machine set-up.

Made in USA.
