Round Blank Ceiling Outlet Covers for 4" Box - Satin Stainless Steel

I chose stainless steel because everything else will rust here in South Florida. Aluminum corrodes in a few months. I drill a one inch center hole and 3 small mount holes to attach the 4K security camera to the cover plate. I route the cat 5 cable through the center hole and attach the plate to the 4 inch round electrical box. The system stayed secure through Hurricane Irma recently. This cover is a high quality product and I recommend it to anyone installing equipment outside.
