Abstract: Apparatuses and methods for hanging frames upon mounting surfaces. A hanger, upon which a frame is hung, is securely attached to a mounting surface, such as a wall. The hanger comprises a two-level, female, mandrel slot for receiving a two-level male mandrel. Additionally, bottom-rail-supports may be used to secure the bottom of the frame to the wall to support the weight of the frame and to immobilize the frame on the wall. A spirit-level device may be used for leveling the installed frame on the apparatus prior to fixing the frame to the wall with or without bottom-rail-supports.

Abstract: The invention concerns apparatuses and methods for hanging frames upon mounting surfaces. The principal apparatus of the invention, upon which a frame is hung, is securely attached to a mounting surface, such as a wall. The apparatus comprises a generally planar body with a protruding supporting rail, alignment notches, spirit level, bracket recess, and mounting holes, and is particularly well suited for use with metal frames with universal assembly channels. The supporting rail of the apparatus is designed to be inserted within universal assembly channels in metal frames, thus securely yet slidably and removably attaching the apparatus to the frame. The invention also includes an adapter bracket to allow the principal apparatus to be used with any kind of frame, and special corner brackets to allow the use of the principal apparatus with unusually heavy or wide frames.
