Hammer Strength Lock Knob Rack Attachment - Heavy Duty Gym Equipment for Weight Racks - Perfect for Home & Commercial Gym Workouts

Hammer Strength Lock Knobs allow users to quickly and easily remove and/or change the location of different modular add-ons, such as the Modular Power Pivot, Utility Peg and Nordic Ham. Each Knob features an inset screw to minimize hardware exposure and paint marring on your uprights. The Knobs also include a small, heavy-duty magnet near the base of the Knob, which reduces lost knobs and allows you to store them when not in use.
