Structures used for dividing, supporting, disguising and/or cladding, for example, modular wall panel systems can include frame members that can include or be in the form of a rail having a panel engaging portion with a generally planar mounting surface configured to accept at least one fastener, the panel engaging portion including first and second lateral sides on opposite sides of the generally planar mounting surface. First and second channels can include side walls extending generally parallel to the generally planar mounting surface, the first and second channels facing away from each other.

A reconfigurable modular partition system having a plurality of different types of interchangeable (wall or ceiling) modules with different types of compatible connection components, each connection component being configured to align with another connection component at an interface to form an interface connection (e.g., channel) for securing the connection components together with one or more universal connection interface members. The interface is configured for on-demand reconfiguration without laborious alteration to aspects of the partition system, modules, and components thereof. Reconfiguration of modules is facilitated by removing the universal connection interface member from the channel, thereby releasing the attachment mechanism and allowing rearrangement of the module(s). Replacement of the universal connection interface member secures the reconfigured modules in place in the rearranged partition system.

A leveling assembly for a wall panel is described. The leveling assembly includes a floor track, a leveling track, and a leveling mechanism. The leveling mechanism comprises a leveling bolt configured to pass through a leveling square nut and into a floor track channel of the floor track, such that rotating the leveling bolt in a first direction causes the leveling square nut to push towards a first horizontal protrusion and a second horizontal protrusion of the leveling track, lifting the leveling track upwards away from the floor track.
