1. A corner fitting comprising:
a sleeve body having a hollow inner space and configured to coaxially fit over a pipe member of a predetermined size; wherein the sleeve body has a first distal end and a second distal end spaced apart from the first distal end in a longitudinal direction, wherein an edge of the sleeve body at the first distal end has two protruding tabs and two recesses, the protruding tabs protruding farther than the recesses in the longitudinal direction, the protruding tabs being diametrically opposed to each other in a radial direction of the sleeve body, and the recesses being diametrically opposed to each other in the radial direction of the sleeve body, such that the protruding tabs and the recesses are arranged alternately around a circumferential direction of the sleeve body, wherein the two protruding tabs and the two recesses of the first distal end of the sleeve body are configured and arranged such that the first distal end of the sleeve body fits over the pipe member of the predetermined size with the sleeve body contacting an outer periphery of the pipe member at the protruding tabs and at the recesses in a state in which a longitudinal axis of the pipe member is perpendicular to a longitudinal axis of the sleeve body and the pipe member is nested in the recesses and between the two protruding tabs of the first distal end, wherein an edge of the sleeve body at the second distal end has a corner cut portion, a protruding tab, and two recesses, the protruding tab protruding farther than the recesses in the longitudinal direction, the protruding tab being diametrically opposed to the corner cut portion in the radial direction of the sleeve body, and the recesses being diametrically opposed to each other in the radial direction of the sleeve body, such that the recesses are arranged between the protruding tab and the corner cut portion in the circumferential direction of the sleeve body, and wherein the corner cut portion is configured and shaped such that the sleeve body fits together with an identical sleeve body on the pipe member of the predetermined size in an arrangement with the longitudinal axes of the two sleeve bodies being transverse with respect to each other with the corner cut portions of the two sleeve bodies contacting each other and with the pipe being nested between the protruding tabs of the second distal ends of the two sleeve bodies. |
