Frequently Asked Questions

What receptacles are compatible with this cover?

This cover is specifically designed for HBL26CM10 (30A) and HBL23CM10 (20A) marine receptacles with 1.60" face diameter.

How does the spring-loaded mechanism work?

The cover lifts up when a plug is inserted and automatically springs closed when the plug is removed, ensuring continuous weatherproof protection.

Is this cover suitable for underwater installations?

No, this IP44-rated cover is designed for above-waterline marine applications where protection from spray, rain, and environmental moisture is needed.

Can this cover be used on non-marine electrical boxes?

While designed for marine FS/FD boxes, it may be compatible with other standard electrical boxes, though marine applications are recommended for optimal performance.

How often should the gasket be inspected or replaced?

Inspect the neoprene gasket annually or after severe weather events. Replace if cracking, hardening, or loss of compression is observed to maintain weatherproof integrity.

What maintenance is required for the spring mechanism?

Periodically operate the cover to ensure smooth spring action. Clean any debris from the hinge area and lubricate with marine-grade lubricant if needed.
