Buying Guide: How To Choose The Right Weatherproof In-Use Cover
- Location and exposure: If you face heavy rain, snow, or sun, prioritize UL/ULC ratings and thick gaskets. UL Extra Duty and Type 3R enclosures indicate strong protection in outdoor conditions.
- Device configurations: Check how many and which types of devices you need to protect (duplex outlets, switches, GFCI). Look for 8-in-1, 16-in-1, or similar configurable systems to minimize swaps later.
- Mounting orientation: Decide between horizontal and vertical mounting. Some covers offer both; consider wall space and conduit direction to select the best option.
- Material and durability: Metal (aluminum or steel) covers are typically tougher and more vandal-resistant, while polycarbonate composites resist weathering and cracking in cold climates.
- Installation simplicity: Quick-Fit mounting systems or EZ Change Pins reduce installation time. Ensure your wall surface is compatible with the mounting hardware.
- Security features: Some covers offer lockable options or gasket integrity that helps deter tampering or accidental openings in windy conditions.
