These new rigid stainless steel rules make the job of finding the center of any piece of material very easy. The zero is in the middle with scales in 1/32 “ on either side. The rule is placed on the object so that the readings at both ends are the same. These rules have a second scale which allows them to be used as regular rulers too. They are made using stainless steel with hard chrome finish with permanent etched in markings. Available in 24” and 48” sizes.
