Abstract
Abstract Corner clamps for shelving and the like having rectangular shelves with notches at each corner thereof and a tubular support member positioned at each notch and secured therein by a corner clamp. The corner clamp consists of a U-shaped strap that extends about the tubular support and has leg portions that extend through slots formed in a bracket that is positioned diagonally across the corner and welded to the shelving. A saddle having a notch in alignment with the shelving notch is secured to the bracket. The strap is tightened against the shelving by a lock bolt positioned below the shelf and threaded through a threaded bore in a cross bolt that extends between the ends of the strap and bearing against the saddle.
