A locking screw feature provides lockable adjustability for the slab-supporting ledge member which supports the heavy slabs used to form the face-wall of mausoleum crypts. The lockability permits the ledge member to be made to be freely slidable in its receiver slot of the hanger body which is connected to the structural concrete of the building; and the ledge-lockability is achieved by a locking screw which passes inwardly through the ledge member, and is forced against the hanger member, thus permitting the fit of the ledge member to the hanger member to be freely slidable. This combination of features not only accommodates the adjustability to be easy and precisely accurate, but also tightly locks the adjusted position. Preferably, the ledge member passage for the locking screw is provided as a inward extension of the ledge member hole which holds the screw which holds the rosette cap which conceals the junction of the slabs.
