20 x 16 x 8 in Waterproof Junction Box IP67 - Inner Door for Custom

Our review of the 20 x 16 x 8 in waterproof junction box finds it best suited for installers and DIYers who need a reliable, weatherproof enclosure with room for neat organization. The single biggest reason to buy is the practical extra inner door that separates sensitive components and makes wiring and mounting tidier. The box is IP67 rated and built from high-grade ABS plastic, so it holds up outdoors without leaking or cracking, while the included mounting plate and brackets simplify installation for a range of electrical and telecom uses.

Key Features

• Extra Inner Door: Provides a separate compartment to protect controllers or sensitive electronics and helps keep wiring and terminals organized.
• IP67 Waterproof: Ensures protection from dust and temporary immersion in water, making it suitable for exposed outdoor installations.
• Premium ABS Construction: High-grade plastic offers impact resistance and electrical insulation while resisting sun exposure and common outdoor wear.
• Easy to Customize: The enclosure drills cleanly without cracking and the supplied mounting plate speeds equipment attachment and layout adjustments.
• Versatile Applications: Fits a wide range of uses from POE switches and CCTV power supplies to solar and irrigation controls, providing flexible installation options.
• Included Hardware: Comes with wall brackets, hinged clear cover and mounting plate so most installations need minimal extra parts.

Who It's For

This enclosure is aimed at electricians, installers, and hobbyists who need a mid-size weatherproof box with organized internal layout for devices like routers, POE injectors, small power supplies, and control modules. The inner door particularly benefits setups that separate low-voltage electronics from terminal blocks or batteries.

Those who need an ultra-compact or fully metal NEMA-rated cabinet for heavy industrial power gear should look elsewhere; this ABS IP67 box is optimized for electronics, solar chargers, CCTV, Wi-Fi gear and similar outdoor or sheltered applications rather than large high-voltage switchgear.

Pros & Cons

Pros

• Sturdy ABS construction and positive customer reports of durability and resistance to sun exposure.
• Reliable IP67 sealing with good gasket and no reported leaks in real-world use cases like protecting power supplies.
• Built-in organization via the extra inner door and supplied mounting plate speeds installation and neat wiring.
• Versatile fit for many small electrical and network devices, saving the need for custom enclosures.

Cons

• The size may be larger than required for very small projects, adding bulk where a compact box would suffice.
