Vertical weatherproof cover for single-gang boxes

The Hubbell HBL9420 is a cast-aluminium cover designed for vertical mounting on FS or FD weatherproof boxes. It accepts receptacles with a face diameter between 2.09 and 2.13 inches and includes the required mounting screws. The self-closing lid helps keep the interior dry when the receptacle is not in use.

Neoprene gasket seals against moisture and dust

A neoprene gasket forms the weather seal between the cover and the box, maintaining protection in wet or dusty environments. The aluminium casting resists corrosion without adding significant weight. UL listing confirms compliance with the applicable U.S. and Canadian safety standards for this product type.

Self-closing lid maintains protection during

Under continuous outdoor exposure the self-closing mechanism returns the lid to the sealed position after each use, preserving the gasket seal over time. The cast-aluminium body and neoprene gasket retain their shape and sealing force through repeated temperature cycles. The cover remains UL listed for the duration of its service life.

Questions about this item

How do I mount the HBL9420 cover vertically on an FS or FD weatherproof box, and which step is often missed?

Fasten the included mounting screws through the cover into the FS or FD box, ensuring the gasket seats evenly; the step often missed is checking that the self-closing lid swings freely after tightening.

What part of the HBL9420 will need replacement after extended outdoor exposure?

The neoprene gasket can harden or crack over time, so plan to replace it when the seal no longer compresses fully against the box.

What is the largest receptacle face diameter the HBL9420 can accommodate without binding?

The cover fits receptacles with a face diameter of 2.09 to 2.13 inches; devices larger than 2.13 inches will not close properly.
