Lowell SM-BR Bridge Rails for SM Series Sound Masking Speakers

The Lowell SM-BR is a purpose-built mounting accessory for integrators and installers working with Lowell SM Series sound masking speakers. Designed specifically for the square enclosure format of those speakers, the SM-BR replaces the factory hangers with a pair of rigid bridge rails that attach directly to the rear of the speaker using six Phillips head screws, all of which are included in the kit.

This approach suits commercial installation environments where a clean, secure mounting surface is required without relying on the speaker's original suspension hardware. The 18-gauge galvanized steel construction provides corrosion resistance appropriate for plenum or ceiling spaces. Installation is straightforward: remove the existing hangers, position the speaker face down, align the rails with the six pilot holes on the enclosure, and fasten with the provided screws. No additional hardware is needed to complete the rail attachment.

For AV integrators specifying sound masking deployments in offices, healthcare facilities, or open-plan commercial spaces, the SM-BR offers a manufacturer-matched solution that maintains compatibility with the SM Series enclosure geometry, avoiding the fitment issues common with third-party alternatives.
