Two laterally extending connecting arms are formed with a pair of laterally spaced longitudinally extending side panels (12) at their respective inner surfaces. There is a mortise-tendon connection (22, 24) between superposed units, with a vertically recessed mortise (22) at the bottom of each connecting arm (18) and a complementary vertically projecting tendon (24) at the top of each arm. The mortises and tendons define a pair of laterally spaced opposed vertical bearing surfaces. Each mortise and tendon is 1/3 the total width of the unit. The connecting arms are spaced from each other by a distance twice the longitudinal spacing of each arm from the adjacent bend of the side panels.
