Abstract
Abstract A cabinet closure system capable of providing both mechanical rigidity and RFI shielding. The closure system has a U-shaped closure element which relies upon a wedging-lever action for securely holding equipment in place. Because of the novel makeup of the closure element, a minimum amount of fasteners are required to secure the closure element in the sealed or closed position. In this manner quick removal of and/or installation of equipment is possible.
