Abstract: A bracket assembly includes a back plate with outer and inner sides and a pin opening extending therethrough. A clasp member has an extending portion and an encasing portion extending from the extending portion. The extending and encasing portions and the inner side of the body define a channel configured to receive a rack beam. A pin seated in the pin opening has a shank, and a head at the outer side of the back plate. The shank extends through the opening into the channel. The shank is configured to engage the rack beam within the channel. The head is welded to the outer side of the back plate. An extension member defines a support surface and includes pair of substantially J-shaped plates and a cover nested with the plates such that it forms the entire support surface and is substantially flush with sides of the substantially J-shaped plates.

Abstract: A shelf is configured for use with a weight rack including first and second vertical members extending generally parallel to each other and positioned in spaced relation to each other. The shelf supports one or more free weights and has first and second opposed ends and front and rear sides extending between the ends, where the first end of the shelf is connected to the first vertical member and the second end of the shelf is connected to the second vertical member, such that the first and second vertical members support the entire weight of the shelf. The shelf may include a rotation limiting structure to limit rotation of the shelf with respect to the vertical members. A weight rack may be outfitted with one or more such shelves, and in one configuration, the weight rack may include a number (N) of adjacent shelf stacks supported by number (N+1) of vertical members.
