This set pairs the height- and angle-adjustable Jammer Arms with Multi-Grip Handles and Weight Loading Pins, giving you a fully configurable station without giving up rack space for barbell work.\u003c\/p\u003e\n\u003ch3\u003eHeight, Angle \u0026amp; Configuration\u003c\/h3\u003e\n\u003cp\u003eEach arm rides on a trolley that slides along the upright and adjusts in height via a mag pin - no tools needed. A second mag pin locks the arm into one of 13 angle positions, so you can dial in an exact start\/stop angle and it stays locked mid-set.\u003c\/p\u003e\n\u003cp\u003eStoppers mount to the uprights independently of the arms and hold your handle configuration in place during use. Because the trolley sits on the outer face of the upright, it doesn't block the J-hook holes underneath - you (or a training partner) can still rack a barbell and squat on the same upright on the inside of the rack while the Jammer Arms are fitted.\u003c\/p\u003e\n\u003ch3\u003eMulti-Grip Handles \u0026amp; Weight Loading Pins\u003c\/h3\u003e\n\u003cp\u003eThe included Multi-Grip Handles attach via a 2x mag pin quick-release and give you a choice of grip positions for pressing movements and deadlift variations.\u003c\/p\u003e\n\u003cp\u003eThe Weight Loading Pins use the same mag pin attachment and let you load weight plates directly onto the arms (up to 250kg per pin) - turning the Jammer Arms into a plate-loaded press station for progressive overload on presses and much more.\u003c\/p\u003e\n\u003ch3\u003eConstruction \u0026amp; Compatibility\u003c\/h3\u003e\n\u003cp\u003eArms are built from 75 x 75 x 3mm steel tube, finished in black powder coat for durability.
