We are proud to introduce a quality pittsburgh lock hammer line with a compact design. The Prolock Pittsburgh Lock Hammer can cut your finishing time up to 80%. It can be used to fold over or "seam" metal up to 20 gauge and lighter close Pittsburgh Lock Seams on ductwork, tubes, doors, panels, etc. Operators require no special training or skill. The finished seam is neater and more uniform than seams hammered by hand. Fabricating plants using adapters claim that one operator's production equals that of eight hand-hammering workmen.
