Radial Air Dampers 6" thru 14"
Works as advertised. Simple and easy.
Works just like advertised. I was freezing in my office. Received quickly. Some Bosses do not realize how cold their employees get. It is miserable if you have arthritis. Ty.
Kit was perfect
Couldn’t find anything like this locally and was about to make my own when I discovered these rings. Added these to new led retrofits and porch ceiling looks new. Be sure to measure the outside diameter of new lights and add at least 1 inch if using new lights like I did. I added to inches to the OD of the new lights and coverage was ideal.
