Very pleased. *by L***P on Reviewed in the United States on October 23, 2024* I bought a Bud JB-3955 WITHOUT knockouts, so i can put my own holes in. Its a nice heavy duty metal box. It measures 6" square x 4" deep. The gray paint looks nice. The holes line up well with the cover. It was a very easy purchase on Amazon. No regrets here. My local stores did not have a box like this in stock. I would definitely purchase this again. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great Auxiliary Box *by M***S on Reviewed in the United States on June 18, 2024* Fantastic auxiliary box to main panel. I located next to main panel and ran two 1" EMT conduits to it. This allowed me to run all my Sense and Emporia circuit monitoring wiring to the BUD Industries box shown in photo to the left. This kept a rat's next of CT monitor wires out of my main panel.BUD provides a nice, inexpensive and good quality box. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Perfect! *by W***R on Reviewed in the United States on July 5, 2024* This worked great to house my ac/DC converter for under cabinet lights. Solid box. ## Frequently Bought Together - BUD Industries JB-3958-KO Steel NEMA 1 Sheet Metal Junction Box 10 L x 8 W x 4 D, Gray - RVBOATPAT Insulated Inline Splice Connector 2/0-6 Gauge Wire Connectors Aluminum to Copper Wire Connectors 7/32" Slotted Allen Hex Insulated Cable Connectors - 5 Pack - RVBOATPAT 2 Port Insulated Multi Tap Connector 4-14 AWG Aluminum to Copper Wire Connectors Single-Sided Entry Aluminum Wire Connectors Slotted Allen Hex - 5 Pack --- ## 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.us/products/14574971-bud-industries-jb-3958-ko-steel-nema-1-sheet-metal](https://www.desertcart.us/products/14574971-bud-industries-jb-3958-ko-steel-nema-1-sheet-metal) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-06*
