Worked great for my needs
Only vent cover that had a larger ****** that covered up an over cut vent hole. Looks great too.

exceeds expectations
Vent covers are much like the jewelry for the home. Functional, attractive design, good engineering, simple ordering process, no skimping on material gauge, impeccable finishing, earth-friendly packaging, timely shipping. Good job!

Great Damper
I have ordered about a dozen dampers from Advantage Mechanical Supply. They have all worked out great. 1 time we had a damaged one and they replaced it, great service. I will continue to use.
