Abstract
Abstract A keeper particularly adapted for multiple drawer assemblies such as used to contain electronic equipment having an elongated nonrotatably mounted and spring loaded sleeve which slidably receives a keeper fitting. A screw-threaded member is adjustably mounted in a screw-threaded bore in the sleeve and is accessible from the end of the sleeve opposite from the keeper fitting.
