ABSTRACT:
A beam for supporting a removable second deck for carrying cargo in a vehicle such as a truck trailer is supported between a pair of opposing tracks on opposite sides of the vehicle. The track has slots formed therein to which the beam is attached. The beam has an end foot on each end. Each foot has a keeper pivotally mounted thereon, the keeper being used to removably attach the foot to the slot. The foot has a notch formed in its bottom surface which engages the bottom edge of the slot. The keeper is spring urged against the foot portion to bring the top portions of the keeper and foot into abutment against each other so that the top of the keeper is in abutment against the top edge of the slot, thereby retaining the foot and keeper in the slot. The foot portion and keeper can be withdrawn from the slot by manually moving the keeper away from the foot against the spring tension.
