AtlasIED 191-78 Enclosure with Adjustable Mounting Bracket

Designed for contractors and integrators who need a reliable, install-ready enclosure, the AtlasIED 191-78 enclosure with adjustable mounting bracket streamlines AV, security and low-voltage installations. The recessed baffle-style enclosure accepts 8-inch loudspepeakers and low-voltage devices while delivering a clean, code-friendly installation. Its adjustable mounting bracket (1/16 to 3/4 inch) provides installation flexibility across varied ceiling types and depths, and the compact 4-inch depth and 11.69-inch width fit common ceiling cavities.

Built from CRS with heavy undercoating and patchjute lining, this AtlasIED enclosure reduces vibration and improves acoustic performance, while four compound conduit knockouts keep wiring organized for surveillance, monitoring and networked audio systems. The durable black epoxy finish resists damage during construction and blends discreetly into finished ceilings. At just 3.5 lb, the unit is easy to handle on-site yet robust enough for commercial applications.
