WE-EF / 134-1748 BDO12-I The installation of ceiling luminaires is often problematic due to rough site conditions during masonry works. WE-EF has developed this unique range of installation blockouts, to be integrated in concrete structures during the initial phase of construction. Later, after the site has been cleared of mortar, sand and debris, the electrician can unpack the luminaire for a fast, easy and cost saving installation. Type I: Installation blockout for proud installation. Luminaire faceplate remains proud of wall or ceiling surface. Made from galvanized steel and rugged MDPE (Polyethylene). Frame die-cast aluminium alloy. Powdercoat finish in RAL9004. Specifications: A: 383 B: 272 C1: 192 D1: 155
