An improved connection for a rack system joining together first and second elongated structural members in transverse relationship. The first member has a plurality of longitudinally spaced aligning holes, each of which include an inside bearing surface, while the second member consists of at least one fastening hole and one load bearing wedge action seating lug. The seating lug is spaced from the fastening hole a distance equal to the longitudinal spacing between aligning holes in the first member. The seating lug is adapted to extend within one of the aligning holes in the first member to position another aligning hole in registry with the fastening hole in the second member. A bolt or other fastener means is then protruded through the fastening hole and the other aligning hole. A cam means on the seating lug engages the inside bearing surface of one of the aligning holes moving the first and second members into side-by-side contact when the fastener is tightened. The unique combination of seating lug and bolt provides a strong, rigid connection reducing lateral and transverse movement in the rack system and providing for safe and easy assembly and disassembly.
