Quam ERD8U Back Box Enclosure, Round, 275 CID, White Powder Coat Finish

Designed for reliable, code-compliant installations, the Quam ERD8U back box enclosure is a professional solution for commercial audio, security and surveillance applications. This Quam Speakers product is a 275 CID round, UL Listed steel enclosure that protects in-ceiling 8" loudspeakers while improving acoustic performance with an internal molded polystyrene damping pad. The durable white powder coat finish delivers a clean, low-profile appearance that integrates with most interiors and resists jobsite wear.

Installers and systems integrators will appreciate the four welded tie-off straps plus two snap-in tie-off straps included for secure mounting and seismic support where required. The compact 12.3" width and lightweight 2 lb construction make positioning and handling easy during monitoring, public address, and security system deployments. Engineered for consistent fit with Quam speaker accessories (SSB-2, SSB-3, SB-4, SSB-6, SSB-7), the ERD8U speeds installations and reduces callbacks.
