I bought as the single four positive and negative were out of stock. Pleased as I'm going to cut in half to give me two separated bus bars, and gives me higher amp carrying too. ### ⭐⭐⭐⭐ Watch the screws! *by J***T on 5 December 2022* This is a great bit of kit but... When mounted on the wall just be careful when taking out the screws. There is nothing stopping them coming right out and dropping down to the depths never to be found again... Like I did! The bolts are M10 which are a bit big, M8 would have been easier as I had to change a lot of lugs to for this to work. Overall it does the job well but it really is majorly overpriced for what it is. ## Frequently Bought Together - Gloaso 12V-48V Copper Bus Bars 400A Marine Busbar Power Distribution Block Heavy Duty 8X 3/8" (M10) Posts Battery Terminal Buzz Bar DC 400 Amp for Automotive/Trailer/RV/Solar/Boat/Marine | Red&Black - TKDMR 10pcs 1/0 AWG-3/8 Battery Lugs,Heavy Duty Wire Lugs,Ring Terminals,Battery Cable Ends,0 Guage terminals,Battery Terminal Connectors with 10pcs 3:1 Heat Shrink Tubing - 10pcs 4 Awg - 3/8" (M10) Sanuke Wire Lugs Ring Terminal Connectors Ends, UL Listed Heavy Duty for Battery Cable Lug Wire Electrical Eyelets with 3:1 Dual Wall Adhesive Heat Shrink --- ## 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.jp/products/473050108-bus-bars-12v-48v-400a-heavy-duty-copper-busbar-power](https://www.desertcart.jp/products/473050108-bus-bars-12v-48v-400a-heavy-duty-copper-busbar-power) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-16*
