16 X 6 (Duct Opening Size) Air Register Adjustable Aluminum Louvers with Damper (Color-White)

IMPORTANT NOTE - Registers are measured by the hole they are meant to cover. For instance, if you have a ceiling opening that measures 8-1/4" x 8-1/4" you would order an 8x8 register. The back part of the register will be undersized to fit about 7-5/8" x 7-5/8". The face of the register will cover up to 9-1/2" x 9-1/2" IMPORTANT NOTE: Metal registers are somewhat flexible. If the item arrives looking imperfectly tweaked, it will straighten out once affixed to the wall or ceiling.
