Just do not over tighten the #3 screw that you run your panel ground to. It will break every time. I did it, then the guy working for me did it. But then I got on Amazon right away, ordered more and we were back in business right before the inspector came. --- ## 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.is/products/16560936-proconnex-42400-intersystem-bonding-bridge-conduit-fitting-1-pack-gray](https://www.desertcart.is/products/16560936-proconnex-42400-intersystem-bonding-bridge-conduit-fitting-1-pack-gray) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-04-29*
