ABSTRACT:
Disclosed herein is an improved combination of a hollow member and a backing member to be inserted therein. Another member such as a hinge is secured to the hollow member by machine screws which extend through the hinge and the wall of the hollow member and are tightened in threaded holes in the backing member. The hollow member is provided with an inwardly extending pawl and the backing member is adapted to be placed in a desired position in the hollow member by engagement with the pawl. When a plurality of backing members are to be placed in the hollow member, a plurality of pawls are formed in the hollow member so that they are laterally offset from each other with respect to the longitudinal direction of the hollow member and a void portion is formed in each backing member so that the pawls above the intended pawl do not interfere with the backing member as it is inserted in the hollow member.
