The T-3 Series Stabilizer Bar by Titan Fitness® mounts to the bottom of your T-3 Series Power Rack, constructed from heavy-duty 2 x 3-inch 11-gauge steel with 2-inch hole spacing spanning the length of the 42-inch Stabilizer Bar. The crossmember connector strengthens the stability of your Power Rack and eliminates the walk-through design. Additionally, this durable stabilizer can be utilized as a Daisy Chain to link multiple T-3 Series Power Racks with different depths in a gym training facility setting for better space efficiency.
