AtlasIED FC‑4MR Mud Ring for 4-Inch Ceiling Speakers

The AtlasIED FC‑4MR mud ring is engineered for new construction installations of 4″ IsoFlare™ ceiling speakers. It secures conduit and wiring to the framing before drywall is installed, maintaining perfect speaker placement during the build.

Featuring durable structural wings for flange attachment, the mud ring doubles as a precise drywall cutout guide. Sheetrock is plastered flush to its edge, creating a clean, recessed opening ready for final speaker install.
