Safety Catch Bars: Solid steel, chrome plated catch bars adjust in height to allow full range of motion and safely contain a dropped bar. Multiple Bar Racks: Six rack heights allow for maximum bar clearance and extend width for wide hand positioning. Bolt-down Holes: For added safety, pieces can be bolted to the floor through predrilled holes. Kick Plates: Made of 16-gauge, stainless steel, kick plates protect equipment for long-life and durability.
