ER-1505
When the sealing surface of the 1505 RiB housing is recessed below the finished grade, preventing proper sealing of the fixture, an Extension Ring(s) must be used to complete the installation. Constructed of die-cast, copper-free aluminum with a black powder-coat finish. A continuous silicone gasket insures a weather-tight seal. Includes four (4) 8-32 stainless steel screws.
