ABSTRACT:
A disappearing anchor for mounting in a wooden surface, for example, a deck surrounding a swimming pool, is provided. In accordance with the invention, a collar member comprising an axial sleeve defining a central aperture and a radially extending flange is provided. The aperture accommodates the upper end of the cylindrical housing of the anchor device, and is mounted, for example by press-fitting, so that the upper surface of the radially extending flange is flush with the upper surface of the cylindrical housing. The anchor and fixed collar are then placed in the wooden deck which is counterbored so that the top surface of the radially extending flange is flush with the wooden deck.
