Abstract
Abstract An equipment lockdown apparatus for locking pieces of equipment such as computer modules, typewriters or the like is disclosed. The apparatus includes a sub-base suitably secured to a desk or other supporting structure and which supports the remainder of the unit for rotation. A base shelf is included together with a pedestal which rotatably supports thereon one or more additional shelves for rotation. Shields are positioned adjacent each shelf to preclude access to fastening elements for the pieces of equipment on each shelf and a key-controlled locking mechanism holds the entire unit in assembled relation thus precluding access to the fastening means whereby the pieces of equipment are securely locked.
