The Hammer Strength Bolt On Power Pivot Rack Attachment is designed for easy attachment to any Hammer Strength rack. The Power Pivot bolts to any Hammer Strength rack and provides a rotating mount that can be used both pushing and pulling barbell movements. Designed with a multi-bushing swivel joint, movement in all directions feels fluid and seamless—just as it should during training. When not in use, the Power Pivot is hardly noticeable and tucks tightly against your rack. Olympic Bar not included.
