Imagine how useful it would be to lock off any measure along your steel rule, and then rapidly mark this distance off again and again, with ease and confidence.
This stop, made for Garrett Wade, is a carefully machined jig that easily slips on and off virtually any of your rules (up to 1-5/16" wide). The base of the stop is 3/4" wide-more than enough to provide solid support for the back of the rule. The brass nut moves easily up and down the threaded rod to clamp the stop firmly in position. Sold individually or as a pair.
