## Description

IP66 External/Outdoor Waterproof Junction Box (86x86x50mm) : desertcart.co.uk: DIY & Tools

Review: Excellent Quality and Weatherproof Performance! - I recently purchased this IP66 Outdoor External Junction Box for a backyard lighting project, and I’m genuinely impressed with the quality and performance. Build Quality: The enclosure is made of tough, durable plastic that feels solid and reliable. The seal around the lid is thick and secure, ensuring a tight, weatherproof fit. The screws are rust-resistant and easy to tighten, and the hinged lid is a great feature for convenient access. Weather Resistance: We’ve had several heavy rains and even a bit of snow since installing this, and the inside has remained completely dry. The IP66 rating really holds up – perfect for protecting connections in harsh outdoor environments. Ease of Installation: Pre-drilled mounting holes and plenty of space inside made it easy to install and wire. I had room for multiple cables and even a small terminal block without it feeling cramped. The knockouts on the sides were easy to remove cleanly with a hole saw. Versatility: I used it for outdoor lighting, but it would be equally useful for CCTV systems, garden projects, or any other low-voltage outdoor wiring. It has a professional look and feels very secure once mounted. Final Verdict: If you're looking for a solid, waterproof, and easy-to-use external junction box, this one is a winner. Great value for the price and definitely built to last.
Review: Good quality - second one of these I've bought. Does the job well and easily fitted to wall with included bracket without drilling into main box.
