Abstract: Disclosed is an anchor assembly especially for use in a plastic wall-panel which comprises a plug formed of a forward section comprising a tapering plastic board-piercing part and an integral ram head, and of a hollow cylindrical section pivotably connected to the forward section. The assembly may further comprise a spike capable of being driven into the hollow cylindrical section, the spike being provided with a cylindrical portion having serrations on its outer surface for bitting into the cylindrical section or ram head and thus being secured to this section or head. The spike is provided with a hammer portion having a length sufficient at least to engage the ram head, as it is driven into the plug, and to cause pivotal of the forward section of the plug and abutment thereof against the concealed side of the plaster-wall panel.

Abstract: At least one post member of the assembly is receivable by the base member of the assembly through an opening in the top wall of the base member. Cam means are mounted on the inner surface of the outer wall of the base member in alignment with the opening for detachably connecting the post member to the base member when the post member extends through the opening to the bottom wall.
