Hubbell Raco PBC100GY Weatherproof Nonmetallic Device Cover, Blank, 1-Gang, Gray

Fits well on my old blue box, going to upgrade said box with a gray one from this company. Sturdy, and the screw mounts are so much better than the nail in blue boxes. Sure they cost more, but being able to adjust them easily AND control where they go without swinging a hammer at your fingers is a huge plus! (I have zero depth perception, it gets interesting!) Screw holes lined up, and it came with the screws to boot. I added a beat of fire rated acoustic sealant around the lip, and I think it would seriously stop water from a hose. Not going to try it, but I really think it's that watertight when a good sealant is added. Will be replacing all my blue boxes with these as I redo the house, a huge help in ease of installation.

I used this for a weather tight box, its four screws and a plastic cover with a gasket. Works fine.

This fits directly over the junction box for this same brand 1/2-3/4. This will fit an existing Carlon brand box as well, they are identical. I only wish this came as a pair with the box but that's conduit for you.

Close off junction box, works as expected.

The cover that came with the box that I ordered had a problem with the screw holes not matching The box screw holes, They were just a little bit of a major streets doing crooked

Great for a jbox cover I needed to drill a hole in it so that I could mount something to it and it worked well.

fit perfectly with Hubbell Bell junction box. Also worked with a different brand of gray box that I purchased at Lowe's. 4 hole style. I used this for 2 different applications. 1) for an entry point for some ethernet cat5e cable coming down out of my soffit from the attic through a conduit into this box, and then back into another attic on a different part of the house. 2) I ran some 20 amp 12-2 electrical wire to a motion light from inside the garage up into the soffit area (through a small section of conduit - see pic) and into the box. These covers work very well and create a tight waterproof seal.

Nicely molded. The material seems tough. I'm quite happy.

Four screws

Go to Home Depot if you can for a better price, but for low quantities this is a good choice.

cover will fit a bit expensive for a plastic cover !
