Torsion grille presents a clean appearance with a contoured edge and no visible hardware. It’s an attractive solution when architectural specifications require ceiling speakers to be void of visible mounting hardware. The grille utilizes welded speaker studs and specially designed torsion brackets with springs to mount into torsion receptacles that are welded into specified Lowell backboxes (order separately). Grille is ideal for upscale offices, hotels, airports, retail, professional buildings, and dining establishments.
