# Retail pallet rack support assembly with reinforced base and replaceable shelf interface adapter

## Abstract

An apparatus reinforces the lower portion of a pallet-rack upright while furnishing a replaceable interface for a floor-level shelf beam. A rigid steel base frame includes a vertically oriented main tube welded to at least one horizontal brace, the members using plate thicknesses of at least one-eighth inch to support rack loads and resist forklift impact. A tubular front adapter post is fixed to and spaced ahead of the main tube; opposed lateral walls of the post present vertically separated apertures. A rack-interface adapter telescopes over the post and is removably secured by fasteners extending through aligned openings in the adapter and post. The adapter carries a vertical series of shelf-engagement slots and defines an internal cavity that clears shelf-bracket lugs. Abutting flanges transfer vertical and impact forces from an engaged beam into the main tube. The adapter can be exchanged without disturbing the anchored base frame or overlying rack.
