Good quality, sturdy box with lots of holes

Good product no issues!
Size: 1/2-Inch
Nothing remarkable; these are well made and as expected, which is a good thing! Quality of construction is good as is the finish. Hardware includes is also well thought out and fits / works.

Solid build, great value for an exterior box
Size: No Size
Great value on this one. Sturdy metal construction will protect the outlet, well built, and mounting was straightforward. Knockouts give you flexibility on which side you want to run conduit through. One thing to plan for if you're mounting on stucco like i did, the box doesnt sit flush against the uneven surface. I ran a bead of exterior polyurethane sealant around the perimeter once it was mounted to keep water from working its way behind it. Wall texture issue, not a product issue, but worth knowing before you start. Otherwise, the box itself water resistant as designed. Hard to beat for the price.

OK, But Non-standard Part
Size: No Size
Installed and working fine on my deck, but it is a non-standard size. Works fine, threads into conduit fine, but not easily compatible with conduit "cable clamps".

Great price for a standard wet location electrical box
Size: 1/2-Inch
Great price for a standard wet location electrical box. These are about half the price of the ones at the big box stores, which are exactly the same. Why pay more for the same exact thing? If you don't need one right away, they are a better deal on here.

Good box
Size: No Size
Nicely shrink-wrapped package keeps the included two plugs and two mounting clips and screws in the package. Well constructed and the threads in the fittings were clean.

Great quality!
Size: No Size
Very thick durable metal and mounting was easy. I had made a custom lamp and this box had the stability I was looking for. I’m not using it in a water located area but with the seals included, appears it would do well.
