SG Armaturen 8249044405 is a surface-mount frame for the Multi Concept 620x620 modular luminaire range, allowing panels intended for recessed installation to be fitted directly to a solid ceiling. The sheet-steel housing measures 613 x 613 x 131 mm and is finished in pure white (25% gloss) to match ceiling grid modules. Screwless terminal blocks accept 220-240 V mains supply for straightforward wiring. Typical application is installing modular office and commercial LED panels in rooms without a suspended ceiling.
