Caliper Accessory Kit, Dasqua 

Convert a standard caliper to an inside/outside point caliper. The different points provided allow for combination applications for specialized uses (e.g. disk brakes). The frames tighten around the calipers jaws extending the length where the points can be used for multiple uses.

Includes two frames, lock screws, Allen wrench, and three pairs of points (1" flat, 1" pointed, 4" pointed).
