AtlasIED P77-8 Plastic Mounting Ring

The AtlasIED P77‑8 is an 8″ plastic mounting ring designed for retrofit ceiling installations, enabling installation from ground level—a perfect solution when plenum space access is limited. Its lightweight polystyrene construction ensures durability without adding extra weight.

Notably easy to install: after cutting a 12″ (305 mm) hole in the ceiling, the ring snaps at its break‑slot and is maneuvered above the ceiling plane. It securely accommodates various 8″ baffle models and includes four J‑nuts for stable attachment.
