Squares

Checking squareness and right angles

Squares check perpendicularity (90° angle) and are used to mark out and align parts.

They come in combination (with graduated rule, level and scriber), solid precision (master, hardened and lapped), hook and double square types.

The hardened and ground blade and heel ensure an exact, long-lasting reference in the shop.
