The Beta Tools Three-Leg Self-Locking Pullers, No. 1517, have a design that includes simultaneously-opening legs which spread out equally together. This design eliminates the problem of setting one leg in place and then spreading another leg and having the previous leg falls out of place. The 1517 comes in four sizes to remove bearings, pulleys and wheels from 1” to 6” diameters. The Three-Leg Pullers have a center plate, which allows users to open the jaws from the rear of the tool. The fully-threaded rod has a hex head top for applying a wrench or socket and the ball-bearing end accepts two interchangeable tips, which are included.
