IP67 Waterproof Junction Box With Latch
This IP67-rated enclosure is designed for outdoor electrical connections. It features a sealing gasket to prevent water, dust, and snow ingress, protecting sensitive components. The virgin ABS construction offers impact resistance and UV stability, while stainless steel latches secure the cover for a tight seal. A mounting plate, wall brackets, cable glands, and a DIN rail are included to support straightforward installation. Best for outdoor electrical projects that demand robust weatherproofing and long-term durability. A potential limitation is that drilling openings may require careful planning to preserve IP integrity.
Who this is best for: outdoor installers, solar projects, and weather-exposed equipment housings needing a reliable, easy-to-customize box.
Key features at a glance
- IP67 waterproof and dustproof certification
- Virgin ABS for strength and insulation
- Stainless steel latches for durability
- Includes mounting plate, wall brackets, cable glands, and DIN rail
90 Gallon Resin Deck Box
This large resin deck box provides substantial outdoor storage space for furniture cushions, garden tools, and miscellaneous outdoor gear. It is designed to stay dry in wet conditions, helping protect contents from rain and moisture. The deck box is best for homeowners and property managers needing a weatherproof storage solution with a lockable lid for peace of mind. A potential limitation is that it is not designed for electrical enclosure purposes; use it strictly for general outdoor storage to avoid misapplication.
Who this is best for: homeowners seeking extra outdoor storage capacity and weather resistance for garden items or pool accessories.
Important considerations
- Waterproofing and UV resistance are key benefits
- Large capacity reduces clutter in outdoor spaces
- Not suitable as an electrical junction box without proper enclosure rating for electronics

Buying Guide: Large Plastic Enclosure Boxes
What to consider when choosing
- IP rating: Choose IP67 for full water ingress protection or IP65 for general weather exposure.
- Material: Virgin ABS provides good impact resistance and insulation; consider UV stability for outdoor use.
- Size and internal space: Check internal dimensions to ensure components fit comfortably.
- Hardware included: Mounting plates, brackets, and glands save setup time.
- Ease of customization: Look for boxes rated for drilling without cracking and with accessible entry points.
Mounting and installation considerations
- Plan cable gland locations to maintain IP integrity.
- Use wall brackets or DIN rails when needed for organization and accessibility.
- Follow local electrical codes for outdoor installations and enclosures.
Maintenance and longevity
- Inspect seals and latches periodically for corrosion or wear.
- Clean exterior surfaces to prevent buildup that can impede proper sealing.
- Store or position heavy boxes to avoid impacts that could compromise the enclosure.
Frequently Asked Questions
- What is the difference between IP65 and IP67 enclosures?
IP65 protects against dust and low-pressure water jets, while IP67 provides complete protection against immersion in water up to a certain depth and duration. - Can I drill into ABS plastic enclosures?
Yes, many ABS boxes are designed to be drilled; do so carefully to avoid compromising sealing integrity. - Which enclosure is best for outdoor electrical connections?
Look for IP67-rated waterproof enclosures with sealing gaskets and stainless hardware for durable outdoor use. - Are these enclosures suitable for outdoor furniture storage?
Some, like the resin deck box, are designed for storage; use dedicated storage boxes for contents and avoid electrical components in non-electrical boxes. - Do these boxes require special coatings?
UV-resistant materials help; stainless latches add corrosion resistance in exposed environments. - What should I consider for mounting hardware?
Ensure mounting plates and brackets are included or compatible with your project layout to simplify installation.
