ABSTRACT:
A wall attached base includes locking members rotatable into overlying relationship with the flanges of a tubular metal frame to confine same adjacent the wall surface. Appendages on the base receive a tool for imparting rotation to the base for moving of the locking members into and out of frame locking positions. Portions of the base frictionally engage the frame to prevent undesired rotation of the base. The frictional portions of the base are yieldable ears formed on the locking members or, in the modified form of the invention, surfaces on the appendages of the base adapted for frictional engagement with the frame. Wall marking pins are provided for temporary installation within each base to precisely mark the wall for installation of screw means.
