Posi Lock manufactures mechanical gear and bearing pullers ranging from 1 to 40 ton capacity and hydraulic pullers 5 to 200 ton capacity. The patented steel Safety Cage design locks the puller jaws securely in place at all times. This prevents the jaws from snapping back or slipping off the work surface. The T-handle opens and closes the jaws for a one-person setup and operation. This substantially increases productivity, tool life and safety for the technician.
