Rheia™ 3" Ceiling Boot Assembly | Part #10-01-220

Where the Duct Run Ends and the Fresh Air Begins

The Rheia™ Ceiling Boot Assembly is the outlet point of the whole micro-duct system, the piece that carries conditioned air out of the ceiling and into the room. It connects directly to 3" Rheia™ duct and ferrules, then mounts into the ceiling drywall and framing so the termination sits clean and flush rather than bulging out of the plane.

Once the boot is set, Rheia™ diffusers and grilles snap straight in, so the finish work happens fast and without hardware showing. Molded from a flame-retardant PC/ABS engineering thermoplastic rated UL94 V-0, it is UL 181C listed and UL 2043 rated for air-handling spaces, and it is 100% recyclable.
