4 in. 20 cu. in. Non-Metallic Ceiling Box with Mounting Screws is rated 1.8 out of 5 by 4.
Rated 4 out of 5 by from When installed properly works just fine This box works perfectly fine when installed according to the instructions. It is intended for a new construction type installation where the proper 2x4 wood backing can be installed priar to the actual fan install. Holes in the box are oversized to allow the screws to pass through the plastic box and into the 2x4 wood backing. The 2x4 supports the fan not the plastic box. Works best if the 2x4 wood backing can be installed before insulation and drywall

Rated 1 out of 5 by from do not buy This box will not accept standard size screws to secure a light fixture. The screw holes are too large. This is a horrible design flaw.

Rated 1 out of 5 by from get your parts right I bought this in a hurry not realizing it was 3x more expensive than similar products (this can support a fan however). The provided screws that you MUST use to mount a fixture to the box according to the instructions were too small. They were the exact same size the box I was replacing had, but too small to grab the plastic. Not something you want to be dealing with when you've got a light fixture hanging and insulation falling in your face while you try to fix something.

Rated 1 out of 5 by from Nope. Screws are expected to pass through the holes into "a 2x4" according to the instructions. What floor or ceiling joist is a 2x4 first off, secondly, I am using a T brace because the floor joist is too far to the side. Should have bought the more expensive metal version with tapped screw holes, this thing is useless.
