ABSTRACT:
Shaped springs are fitted to a flange of a modular package such as a sink-disposer unit inserted through an aperture in a surface. One camming surface moves each spring out of the way during insertion of the package into the aperture and a second camming surface sprung outwardly against the wall of the aperture to obstruct removal of the package as insertion is completed. The spring may then be selectively tensioned by a threaded nut.
