The clean design of the Homebox gives it a look that is both timeless and modern. The exterior letter plate is made of high-quality, brushed aluminium and the in-door sleeve is made of ABS plastic. The interior letter plate is available in grey (RAL 7047), cream (RAL 9001) or white (RAL 9010). The Homebox fits virtually any door or door frame, new or existing. It is designed as an in-door sleeve and is easily mounted from the inside with two screws. With its extendable sleeve construction, the Homebox can accommodate a variety of door or door frame thicknesses. In standard form it fits doors from 38 mm to 70 mm thick and comes complete with the necessary mounting hardware. With the in-door sleeve extender, the door thickness can be as much as 100 mm.
