Abstract
Abstract A removably mounted swimming pool safety rope anchoring device for a pool with a metal, wood or fiberglass wall and a vinyl liner includes a stem having an enlarged portion at one end, and threaded along its whole exterior; a nut which can be threaded on the smaller end; and an eye part having an internally threaded socket portion which threadedly engages the enlarged portion of the stem and an eye rigid with the socket portion. This is inserted through the wall during the installation of the pool with the nut on the outside and the stem extending through a hole in the pool wall. A lock washer and a sealing washer are arranged between the nut and the pool wall. A hole is cut in the liner to allow the enlarged portion to project through, and the portion of the liner around the enlarged portion is overlaid and clamped by the socket portion. This permits the eye part to be removed and the liner to be changed without requiring access to the nut on the outside of the wall.
