Shimeyao Plastic Flat Blank Plate Wall Hole Cover Ceiling Outlet Cover, Electrical Box Plate with M3.5 Screws for Ceiling Fan Light Switch Junction Box(26 Pcs,5 Inch in Diameter)

Easy to use blanking plates. Can be screwed in place, or glued along the narrow edge if that's what you need. I've had these outdoors covering up some old holes in the fascia where lights used to be, and after 2 years they still look as good as new. No yellowing, and they aren't brittle or damaged despite being in the sun.

I got these to cover electrical boxes in my ceiling where light fixtures had been removed. These were flimsy and that was the good thing. The screws provided did not fit my plastic electrical boxes. They were way too small. To top it off, the screws had silver heads. Not sure why anyone would order white covers if they didn't want the screws to match. I'll replace with a different brand.

Cheap and good quality

these are literally just plastic discs. They will work for covering the holes but are not very appealing to the eye.

It was what I needed to cover a hall ceiling 5 inch hole after removal of a wired smoke detector. The screw holes were correct at 3 and 1/2 inches. This item came with long mounting screws (not painted white) and did not do great with a textured ceiling. VERY flimsy and thin. Metal cover would have been much better however the 3 1/2 screw distance box made it hard to find. I could not use the first cover ordered from Amazon of 4 1/8 round metal cover since it did not completely cover.

This was a good product for a quick fix I needed but the plastic is pretty cheap.

For reference these things are about as thick as a plastic milk jug. In my opinion completely usless for the advertised use. I would not recommend buying these unless you want thin translucent disc's with small holes (some the holes were not punched all the way).

Didn't fit; had to return them.
