US Patent 7744178 Rack-mounted rail system

A racking system for storing equipment in a rack includes a rail that is configured to be attached to the rack and a housing that receives the equipment. One of the housing and rail includes a catch, and the other of the housing and the rail includes a slot for engaging the catch. The catch is movable between a first position and a second position. In the first position, the catch engages the slot and extends away from a surface of either the housing and the rail, and in the second position, the catch is withdrawn from engaging the slot. The catch rotates upon moving between the first position and the second position, and the catch is biased towards the first position.
