Rheia™ Metal Floor Diffuser — 4" x 10", White | Part #00-04-300

Built to Be Walked On, Vacuumed Over, and Forgotten About

Floor registers take more abuse than any other part of a ventilation system. The Rheia™ Metal Floor Diffuser is stamped from heavy-duty steel rather than molded plastic, so it shrugs off foot traffic, furniture legs, and vacuum wheels without flexing or cracking. The clean white finish blends into painted trim and light flooring alike.

It drops into standard 4" x 10" floor openings and integrates directly with the Rheia™ single (#10-01-280) and dual (#10-01-310) floor boot assemblies. An integrated adjustable damper lets you balance airflow room by room after the system is running.
