The Bose Professional AMM108 U-Bracket allows for versatile mounting of a single AMM108 loudspeaker with ample rotation to accommodate various pitch angles. The structural rigidity of the bracket allows either two-point attachment to flat surfaces such as walls or ceilings, or single-point attachment via the center mounting hole to secondary support structures such as third-party lighting-pole mounting kits or truss. The bracket fits the M10 × 20 mm threaded inserts on the side of the AMM108 loudspeaker, is shipped with required fasteners for attaching the U-bracket to the loudspeaker and is not intended for permanent outdoor installation.
