Teardrop Pallet Rack Starter. The pre-configured starter and add-on industrial storage rack system is made of durable heavy-gauge steel, includes two upright frames and two pairs of shelf beams. The heavy-duty, one-piece 13-gauge steel uprights feature a long-lasting epoxy finish and allow height adjustments at 2" increments for easy beam placement. High-strength 15-gauge steel beams have a 1-5/8" H step beam design that accommodates cross bars and decking, while the beams provide a secure connection to the upright frame using a positive 6-way locking action which automatically snaps into place and secures the beam. The gauge-welded base plate anchors upright to floor and distributes weight evenly for added stability. Easy assembly. 1-Year Limited Warranty.
