I updated the switches and plugs on a house built in 1970. There were 3 outlets in a room, all a slightly different height, and buried partway in a shelf. I brought the wires forward , mounted these on top of the shelves and it looks so nice. I hate having to cut wall plates. Especially 3 different sizes. There are several holes in the back of the box, and I was able to find the right hole configuration for each one to mount securely to the holes in the electrical box. I had to make a couple of the holes larger, which wasn't a problem since these are plastic. And no visible exterior knockouts. More room and flexibility than a wiremold extension box. ## Features - Surface Mount Housings and Back Boxes work in places where it may not be practical to add a wall box - Surface Mount Boxes and Back Boxes have breakouts to match common surface mount raceway systems - White Box depth is 145 inches - Leviton's color matching wallplate series - Commercial quality product line ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00332F4I0 | | Best Sellers Rank | #43,018 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #73 in Electrical Outlet Boxes | | Brand | Leviton | | Brand Name | Leviton | | Color | White | | Customer Reviews | 4.5 out of 5 stars 529 Reviews | | Finish Type | Painted | | Global Trade Identification Number | 00078477963548 | | Included Components | 42777-1WB | | Installation Type | Surface Mount | | Item Dimensions D x W x H | 1.45"D x 4.5"W x 1.45"H | | Manufacturer | Leviton | | Material | Plastic | | Model Number | 42777-1WB | | Part Number | 42777-1WB | | Product Dimensions | 1.45"D x 4.5"W x 1.45"H | | Specification Met | Ul | | Style | Compact | | UPC | 078477963548 | | Unit Count | 1 Count | | Warranty Description | Manufacture | ## Product Details - **Brand:** Leviton - **Color:** White - **Material:** Plastic - **Product Dimensions:** 1.45"D x 4.5"W x 1.45"H - **Style:** Compact ## Images ![Surface Mount Backbox, Single Gang, 1.45", 42777-1WB, White - Image 1](https://m.media-amazon.com/images/I/410jhi6locL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great *by C***I on January 6, 2026* Works great for installing UniFi in-wall AP in a garage. ### ⭐⭐⭐⭐⭐ Lifesaver *by G***B on October 7, 2025* These were a lifesaver.

I was please to discover that the back snaps off the box, making it easy to work with. Mounted the back plate, hooked up the duplex then snapped the box back in place. Clean look since the only knock outs is in the back plate ## Frequently Bought Together - Leviton 42777-1WB Surface Mount Backbox, Single Gang, White, 1.45" - Leviton 42777-1WA Surface Mount Backbox, Single Gang, White - Leviton 42777-2WB Surface Mount Backbox, Dual Gang, White, 1.45 Inches --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/12138722-surface-mount-backbox-single-gang-1-45-42777-1wb-white](https://www.desertcart.hk/products/12138722-surface-mount-backbox-single-gang-1-45-42777-1wb-white) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-14*
