T-H Marine FD-4-DP Floor Drain And Vent Cover - Black, 4"

Both FD-2 and FD-4 are designed with a flange molded into part to fit into hole so that cut or raw edges are hidden by floor drain for a more efficient, attractive installation. This attractive cover will work on fiberglass or carpeted surfaces and is great for deck drainage, but also mounts as a vent for compartments and pontoon furniture. T-H Marine's FD-2 and FD-4 Floor Drain and Vent Cover's are available in either black or white.
