Abstract: A wedge-lock for a rack mount system having a top plate with slots formed in each end. A bottom plate is disposed adjacent the top plate, and has an incline surface at each end, with a channel formed between the two inclines. Wedge blocks are disposed between the top plate and the bottom plate, with one wedge block at each end. Each wedge block includes an incline surface, a receiving channel formed from the incline surface to an opposing end surface, and a guide for engaging the slot of the top plate. A tensioning member passes through the receiving channels of the wedge blocks and the channel of the bottom plate, thereby retaining the wedge blocks to the bottom plate. As the tensioning member is tensioned, the incline surfaces of the wedge blocks ride up on the incline surfaces at both ends of the bottom plate and cause the top plate to be forced away from the bottom plate.
