WB-4T torsion grille presents a clean appearance with a contoured edge and no visible hardware—an attractive solution when architectural specifications call for a speaker grille to be void of visible hardware. Small profile utilizes welded speaker studs and special devices to mount in torsion receptacles welded into specified Lowell backboxes (order separately). It’s ideal for offices, hotels, schools, airports, medical, retail, and commercial facilities.
