These tapes are made of annealed steel with a protective coating and can be mounted directly on the top or front of your bench.
The center-finding tape has normal Imperial graduations on the top edge and half-scale graduations on the opposite edge. To find the center, find the identical measurement from the top scale on the lower scale.
The other tapes are available in a variety of lengths, with Imperial or Imperial/metric scales, and have measurements that run right-to-left or left-to-right (standard).
The adhesive backing will bond to any clean, dry surface.
