Shimeyao 6 Pack Ceiling Round Cover Plate 20 Pcs M3.5 Screws 4.3" Junction Box Covers Holes Spaced 2.7" White Round Blank Covers Flat Electrical Cover for Fan Ceiling Light Junction Box Switch

good purchase

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.

For the 4.3" cover plate the description says, "distance between the 2 screw holes is about 2.7 inches". However the drawing shows a 2.5" distance. Which is correct? 2/10" difference results in these not fitting the outlet box.

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.

These covers have some good points and bad points. On the good side they are thin and flexible. This allows them to let wires to pass out without major modifications to the cover. Also they can easily be cut with a good pair of scissors allowing them to fit in tight spaces. On the bad side they come with M4-0.5 screws (the description says M3-0.5 which would be even smaller) with a cone shaped neck witch doesn’t fit any standard US electrical fixture. The screw neck should be flat to increase the holding power with the thin cover. The cone shaped neck could easily be torqued right through the thin flexible covers. They might work on a plastic receptacle box but a standard US octagon box takes an 8-32 screw for a cover. So the M4’s are too small to work for a round plastic light box. The price point was good, but it could be even better if they skipped the screws.

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.

DESCRIPTION is INCORRECT: "Suitable Dimension: 2 screw holes is about 2.7 inches, which is suitable for 3.5 inch electric boxes". Unfortunately, the screw holes are ONLY 2.5" apart - Need to be 2.75 inches apart for 3.5 inch electric boxes.
