ORIGINAL FLUSH WITH FRAME

Our "original" Grill Works design, engineered to satisfy the demands of professional floor layers. Each vent is built oversized to cover a standard adjustable metal register installed on the subfloor. The ability to control air flow is retained. The patented design allows flush installation in a 3/4" floor. Fluted dowel construction.
