The junction box was perfect for my needs. I was impressed with the seals and overall quality of the junction box until I came to screwing the lid on the box. The manufacturer included the cheapest screws I've ever seen. One of the screws lacked slots in the head and was useless! My recommendation to the manufacturer is to get rid of the cheap screwdriver included and spend the money on higher-quality screws. ## Frequently Bought Together - Helunsi 2 Pieces Waterproof IP68 External Junction Box, 2 Way Outdoor Junction Box, Underground Plug Line Coaxial Cable Connector Wire Range 5 to 15mm Electrical Power Cord Weatherproof Boxes - Black - Helunsi 2 Pcs Waterproof Junction Box 3 Way, IP68 External Waterproof Electrical Junction Box, Black Underground Junction Box Outdoor Cable Connector, for Diameter 5mm -14mm Wire Gland (Larger) - Junction Box Outdoor Waterproof IP68, 2Way M20, Electrical Boxes Extension Cord Repair kit Coaxial Underground Cable Connector 2PCS --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/142298322-ip68-waterproof-external-junction-box-2-way-outdoor-junction-box](https://www.desertcart.lk/products/142298322-ip68-waterproof-external-junction-box-2-way-outdoor-junction-box) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-09-29*
