Rheia™ Dual Duct Wall Boot Assembly — 2 x 3" Ports | Part #10-01-320

Twice the Duct, One Clean Wall Outlet — For the Rooms That Need More

Some rooms simply ask for more air: the sunny bonus room over the garage, the primary suite, the finished basement zone that never quite keeps up. The Rheia™ Dual Duct Wall Boot Assembly brings two 3" Rheia™ ducts into a single wall terminal, doubling the delivery to that space without adding a second visible outlet or redesigning the layout.

It mounts recessed between standard wall studs and accepts Rheia™ wall diffusers, so the finished result looks like every other outlet in the house while quietly moving more air. 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.

Key Features

Dual 3" Duct Capacity — Combines two 3" Rheia™ ducts into one terminal for increased airflow to individual rooms and higher-load zones.

Fits Standard Stud Bays — Recessed in-wall mounting designed to sit between standard wall studs.

Accepts Rheia™ Wall Diffusers — Finishes with the same diffusers used across the rest of the system for a consistent look.

Flame-Retardant Engineered Polymer — PC/ABS blend rated UL94 V-0 for use inside wall cavities.

Plenum-Space Rated — UL 2043 tested for heat and visible smoke release in air-handling spaces.
