Better than what I needed!
Deep boxes are extremely difficult to find here in Hawaii. Am retrofitting an old house with shallow surface mounted old boxes. New upgraded outlets are deeper and more room is required. Pleasantly surprised that this product is TWO PIECES! Base plate screwed in and notched box snapped in over wiring. Made my job so much easier. Looks good. Note: This is not a heavy duty box. Works for me.

Clean Install Made Easy: The Backbox That Delivers a Professional Finish
The Leviton 42777-1WA Surface Mount Backbox is one of those simple components that makes a big difference in getting a clean, professional install.Right away, the build quality stands out. It’s made from solid, durable plastic that feels sturdy and reliable—not flimsy like some lower-end options. Once mounted, it holds everything securely in place and gives you confidence that your connections are protected.Installation is straightforward and hassle-free. The design makes it easy to work with in both new setups and retrofit situations, especially in areas where cutting into the wall isn’t ideal. Surface-mount back boxes like this are specifically designed for those scenarios, making them perfect for hard-wall or open-office environments .The 1.89" depth is a great feature too. It gives you plenty of room for cable management without feeling bulky, and it works seamlessly with compatible wall plates like Leviton QuickPort systems. Everything lines up cleanly, resulting in a polished, professional look.Another nice touch is the multiple cable entry points, which make routing wires simple and flexible depending on your setup.Overall, this is a reliable, well-designed backbox that does exactly what it’s supposed to do—clean installs, solid protection, and easy setup. If you’re working on low-voltage wiring and want a neat, professional finish, this is a great choice.

Decent product, but the box isn't 1-piece and they are angled funny
This is a decent product, but there are 2 things I dislike. And I was using them in a boat, which might be more unique than typical home/garage installation (although my issues do apply as well).#1 - the box is angled, ie the back where it meets the wall is larger than the face. The 4 sides angle inwards for some cosmetic reason. The practical problem is if you were to attempt to install these where say a horizontal surface meets a wall (like say atop a countertop or work bench that is attached directly to a wall) - the little cosmetic twist makes it so there will be a funny gap underneath the box and you can't fasten it to a horizontal surface. Or similarly, if you put two of these next to eachother, there will be a funny angled gap between them since they are not a square box.#2 - the backside of these snaps into place, ie the box you see in the pictures is not one piece of plastic. I do not know why they do this, there isn't a reason to take the backside off when installing them. And the trouble is, if someone bumps into this box and unsnaps the backside (which is how you mount it to the wall) the other part of the box along w/ the outlet is going to be dangling with exposed wires.

Proven, child safety.
Absolutely no issue with my purchase.Installation was smooth.Not easy for a child to plug something in. Some adults might even have a challenge. 🙂

Leviton Surface Mount Backbox
Just got this and it was easy to install on a wall. The back plate can be easily removed from the sides and placed with exact position then the box or sides can be easily snaped back into place. Comes with out the screws so you will need to buy them and wall anchors.

Very good box
Very nice

Well made & solid.
Very well made and solid construction. I like the cutouts in the back and the different options to attach it to a wall, etc. It's also nice that the back detaches from the sides -- that makes it easier to mount.And while there's an outline showing how you'd make cutouts in the sides, you have to make them yourself, say with a drill or hacksaw.

Electrical box
Too thin and not sturdy. Returned for refund.

Cumple con su función
Se requiere remplazar las chalupas de acero/aluminio y hacer un hueco un poquito mas grande, pero un albañil lo realiza con mucha facilidad. Sirven para poner los contactos de audio de manera excelente.

Great product
I really like this box, enable the wires to breathe due to some nice grooves behind the box. You can snap off any predetermined holes in the back so that you can pass wire.Fits perfectly in my wall and respect code dimensions.I recommend this box

Great solution
Perfect for adding outlets in my sunroom where I have no wall cavities. Super happy they came in black to fit my decor choices!
User
Easy to work with.
Functions well for a non (in wall) installation.I did gave the option for an in-wall box install so this box served well for an on wall installation.
