Vertical weatherproof cover for 1-gang boxes

The Hubbell HBL3054 is a single-gang vertical cover designed for wet or damp locations. Its self-closing lid and neoprene gasket seal against moisture when the outlet is not in use. The grey thermoplastic elastomer body resists impact and UV exposure. It fits a standard 1.36 inch diameter device opening.

NEMA 3R rating and self-closing lid operation

The cover carries a NEMA 3R rating for outdoor rain and sleet protection. The spring-loaded lid closes automatically after a plug is removed, maintaining the seal without user action. The neoprene gasket compresses evenly against the box face to block water ingress. No moving parts are exposed to direct weathering.

UL and CSA listed for code compliance

The assembly is listed to both UL and CSA safety standards, satisfying most North American electrical codes for outdoor receptacles. The thermoplastic construction will not corrode or conduct electricity. Mounting hardware is not included, so installers must supply screws suited to the box material. The cover adds no smart features or connectivity.

Questions about this item

How do I mount the HBL3054 vertically and what step is often missed?

Mount the cover vertically using the supplied hardware; the step often missed is seating the neoprene gasket fully before tightening the screws to maintain the NEMA 3R seal.

What maintenance will the HBL3054 need over time?

Inspect the neoprene gasket and thermoplastic elastomer lid annually; replace the gasket if it shows cracking or compression set to keep the watertight rating.

What is the first limit reached under sustained outdoor exposure?

The neoprene gasket will degrade from UV and temperature cycling before the thermoplastic elastomer body, so plan to replace the gasket first.
