How does this outlet box keep outdoor power safe and dry?

The WILAWELS box uses a snug internal gasket and a hinged, lockable lid to seal the receptacle when not in use. The ABS enclosure resists UV and impact, while the design directs water away from the internal terminals, helping maintain a reliable connection in wet conditions.

• Internal waterproof rubber gasket forms a tight seal around the cover.
• Lockable, flexible lid prevents accidental opening and reduces tampering.
• Durable ABS housing resists weather, wind and light impacts.
• Recessed receptacle placement reduces direct water exposure.
