U-Brackets secure and safely aim loudspeakers from structural surfaces including; walls, ceilings, under balconies and overhangs. Loudspeakers rotate within the arms of the bracket to provide one axis of rotation. Flexible features allow these mounts to be installed anywhere, under trussing, atop tripod stands or suspended from overhead with pipe or threaded rod. English standard hardware and sound isolation gaskets are included in the kit and metric hardware is available separately (see below). For anchoring to wall studs, mounting holes are offset in the brackets’ base on 12”, 16” and 20” centers. Side arm slots increase the bracket’s range of installation positions relative to the wall and sound isolation gaskets add a friction lock to help block sound from between the speaker and the wall.
