Abstract
Abstract The u-shaped detachable handle, for use with paint cans and other receptacles having bails, has a base plate, a connecting plate and a grip extending horizontally above the base plate. The handle is anchored to the receptacle by a rim hook which engages with the receptacle rim and a cam latch mounted to the lower surface of the base plate which seats against the receptacle wall. The handle is also anchored by the receptacle bail which is received by a hook formed at the remote end of the handle. A handle cover surrounding the grip cushions the detachable handle.
