T-Bolt pallet rack has a good, secure design. “Yes, but why is it named T-Bolt?” you ask. Well, my guess is that T-Bolt rack utilizes a bolt with a “T” head in its upright-to-beam connection. When connecting the beam to the upright, a “finger” tab at the bottom of the beam clip fits into the upright column slot at the desired height. This holds the beam in place while a T-bolt is inserted through the beam clip and upright column. Turning the T-bolt 90 degrees and tightening the nut on the face of the beam clip secures the beam in place.
