Abstract: A double-wide, drive in storage rack assembly for supporting loads on pallets including horizontal truss beams and stiffener panels at load-supporting levels constructed to increase the rigidity of the rack and/or minimize the amount of steel used in the rack. In some examples, the storage rack assembly includes mill-building bracing.

Abstract: A spacer for adjusting the width between rollers of roller tooling for machines operable to form metal products has an annular male member with lateral bosses and an annular female member having different depth pockets accommodating the bosses to adjust the combined width of the male and female members.

Abstract: A storage rack has upright columns supporting vertically cambered beams having step box or channel shapes accommodating a generally horizontal deck for carrying pallets and product loads. The beams have upward cambers or convex curvatures that increase the load carrying capacity of the rack.

Abstract: A protector for an upright column of a product storage rack has a V-shaped body with flat side walls joined to a convex curved vertical apex section. Pairs of studs cooperate with keyhole slots in the column to releasably mount the protector on the column. A releasable latch mounted on the protector engages the column to prevent removal of the protector from the column. The latch can be moved out of engagement from the column to permit the protector to be removed from the column.

Abstract: An object and bulk material holding container having a floor attached to corner units for supporting upright walls. The corner units have enclosed pockets for receiving lower ends of the posts joined to the walls. Cooperating notch and tabs on the posts and corner units function in conjunction with the lower ends of the posts to hold the walls in generally upright positions. Foldable gates extend adjacent posts. The gates can be folded down onto the top of the floor along with the walls to place the container in a collapsed storable condition. In one form the floor has laterally movable extensions that are locked in selected positions to change the width of the floor.
