WE-EF / 190-9031 Installation blockout BST13-II The installation of wall 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 II: Installation blockout for flush installation. Made from aluminium alloy. Powdercoat finish in RAL9004.
