Rated 5 out of 5 by The 18 in. baseboard diffuser worked wonderfully for me! I am a 72 year old woman who is redecorating my foyer and my old register was coated not only with thick white paint but also rust that was causing the paint to peel. This register was easy to install and I didn't have to paint it before installing. Fit perfectly and looks fantastic. April 15, 2014
