FITMENT ??Fits 4 inchx10 inch floor vent opening (duct opening). Actual damper box size is 3.75 inch x 9.75 inch. Oversized faceplate covers flooring imperfections around the vent.
??OW TO MEASURE ??Measure the vent opening in your floor, inside edge to inside edge; do not measure your old register, and order the size that matches the vent opening, as a slightly larger opening than 4x10 is normal and will fit this register
??ASY DROP-IN INSTALLATION ??No tools, glue or special skills required. Simply remove your old register and drop this one into the existing floor vent opening for an instant upgrade to your air vent covers.
??URABLE, QUIET AIRFLOW CONTROL ??Recycled high-impact polystyrene damper box will not rust or seize like metal dampers. The built-in lever makes it easy to open, close, or adjust airflow for optimal warm or cool air while operating quietly without rattling.
??RIENTAL DESIGN, RUBBED BRONZE FINISH, FILTER READY??Oriental pattern in a rubbed bronze finish complements most flooring and d?cor styles and works with the Decor Grates filter retainer & filters (sold separately) to help trap dust & debris at the vent
