Abstract: A storage rack having a column with a front flange and side flanges engageable by a clip mounted at one end of a load support is provided with an improved locking assembly for releasably fastening the load support clip to the column. The locking assembly includes an L-shaped connector member comprising a threaded shank extending through a hole in the clip and through one of a row of apertures in the front flange of the column and a lug engaged inside the column. A nut threadedly engaged with the shank has an integral annular flange which engages the front of the clip when the lug engages the rear of the front flange of the column. The lug is bent at less than an orthogonal included angle with respect to the shank from a material which affords elastic flexure of the lug relative to the shank when the nut is tightened to provide a locking action.

Abstract: A storage rack having columns with apertures releasably mounting load support brackets is provided with clean-outs at the base of each column to enable foreign matter which enters the columns to be removed from the insides of the columns. Each column has a front flange and side flanges with bottom edges which engage a base plate. The front flange has a lower edge defining an upwardly-narrowing recess at the base of the column. A pair of gusset plates with inturned deflector flanges extend upwardly from the base plate and along the side flanges of the column. Each gusset plate has a recess in its lower edge, and weldement in each gusset plate recess secures the side flanges and the gusset plates to the base plate.
