## Description

Product Description Snap-On Ceiling Fan Cover Plate - Cp-3540 From the Manufacturer Arlington CP3540-1C 3-1/2 Inch and 4 Inch Ceiling Box Cover.

Review: Solved a problem covering unusually sized junction boxes - We had 2 unusually sized ceiling junction boxes and after searching our local hardware store for hours I stumbled upon these. Problem solved! I was able to mount these to those oddly sized junction boxes very easily. And they can be painted, so they blend fairly well into the ceiling. Of course they remain visible, but they are not nearly the eyesore that having mismatched covers were. And there are no visible screws so in my opinion these are a cleaner install than those mounted with screws. With these there is a plastic bracket that mounts to the box (which bracket is very versatile as far as sizing of the box goes) and then these just "snap" into that bracket. And if we need access to the wiring in those junction boxes it is simple to do so. I can have these down in seconds without tools. And then just as easily they go back up in seconds. In fact our electrician had to remove and replace the one next to the light fixture in order to mount that box, and gave us a "thumb's up" for using them. They are not flush with the ceiling, but again, they are quite easy to remove and replace, fit the boxes very nicely, and were simple to install with just a screw driver. If you have a junction box of odd size these could work for you, too!
Review: The Great Cover-Up - Exceptional fix. Works perfectly.

Exceptional fix. Works perfectly.

### ⭐⭐⭐⭐⭐ Convenient and looks good
*by C***. on January 20, 2024*

I've used this cover several times now and I really like how clean it looks. There is a big difference when there aren't any visible screws in the cover plate. My biggest issue is the screws that are provided. They are not a standard bit shape and strip easily.
