Amacoil/Uhing's Easylock Shaft Collars
Easylock shaft collars have hold reels, spools and other objects in place on shafts. Objects are held firmly between two pintles, one of which has a clamping force control. The clamping control permits adjustment of the holding force from 90 to 1124 pounds. A conical point mounted to each pintle is the mechanism for engaging the object with the shaft.
