The EZ mount flanged enclosure for 8" loudspeaker. Accommodates a wide selection of atlas sound baffles. The EZ mount enclosure/rail system transfers the composite weight of the loudspeaker, baffle, and enclosure to the ceiling’s support members via adjustable support rails (included). The rails may be adjusted vertically and then secured to the specially designed, pre-mounted enclosure brackets with screws (furnished). No tile bridge or time-consuming screw mounting is necessary.
