Rated 4.3 out of 5 by 12 reviewers.
Rated 5.0 out of 5.0 by Just what our wood ceilings needed Wanted to stay with the cast iron look throughout the house and these vents did just the trick. This company did not have this style in a ceiling vent--but hey no problem, drilled 2 small holes and used black screws (bought at HD of course) and we were in business. Really looks good against our wood ceiling and everyone comments on how beautiful they are. July 19, 2014
Rated 5.0 out of 5.0 by Love the look We just had hardwood floors installed and the registers look wonderful.Just what I wanted. June 2, 2015
Rated 3.0 out of 5.0 by Grates are great...but I was disappointed to find the 4x10's in the stores but having to special order the 4x12's (which they carry brass, nickel, white and wood in the stores...just not black). The most irritating part was the $22 shipping charge for 3 grates that cost a total of $30. Buyer beware. September 8, 2006
Rated 5.0 out of 5.0 by Minor Detail. Major Impact I purchased these floor registers to replace the standard brown builder registers that were installed when our home was built. I am very pleased with how these held up. The register is metal and the damper box is plastic. I have removed the product periodically to clean them and they clean beautifully and have worked like new every time. Yes, if I vacuum over them I need to make sure that I did not close the damper. We are moving into a newly built home again and I came onto this site to check to make sure that these are still being made so that we can purchase these for our new home. August 22, 2014
Rated 5.0 out of 5.0 by perfect! Looks great and fits our 1970s house! This item makes our house look updated and looks great next to new floor. December 24, 2013
Rated 4.0 out of 5.0 by fit perfectly. These replaced old brown metal grates. They look great, fit perfectly. Was a little disappointed in the plastic vents. We will see how the hold up. October 4, 2013
Rated 2.0 out of 5.0 by Looks good but doesn't work great I loved the look of these vents so we bought them for the whole house. Didn't realize the vent easily opens and closes. We have to go around and make sure all the vents stay open and we have even taped a few open. January 14, 2014
Rated 4.0 out of 5.0 by Good product, poor shipping service Purchased as gift. Don't yet know if they fit well etc. but the product looks good. The handling of the order was very poor - 4 grilles ordered but shipped (and received) separately in 4 different boxes? "More Saving....."? I'm sure UPS liked that. January 3, 2012
