Description

A stainless steel ruler with cutouts to identify joints, in addition to an inch rule. Features: Double-sided ruler made of stainless steel, all features engraved. Side A has an inch rule along the top (0in-6in), and along the bottom is "BOX DIAMETER OF COUNTERBORE". To the left are the "4 THDS. PER IN.-60°" cutouts on the bottom edge.
