FIRE LOSS IN THE UNITED STATES 2008

A rail and wall support installation includes an adapter which mechanically couples a wall support having a rotatable locking cam portion to an undercut groove on the rear of the rail. The adapter serves both as a mechanical attachment point for the rail to a wall support and to transfer the camming action of the locking cam portion to the rail. The adapter allows existing wall supports to be used with rails that are not directly compatible with the locking member, such as pre-existing rails.
