Leviton Glass-Filled Thermoplastic 1-Gang Industrial Grade Self-Closing Weatherproof Cover

The Leviton Glass-Filled Thermoplastic 1-Gang Industrial Grade Self-Closing Weatherproof Cover is purpose-built for demanding indoor and outdoor electrical installations where ongoing device protection from moisture, dust, and impact is a priority. Constructed from glass-filled thermoplastic, this 1-Gang cover is engineered to Industrial Grade standards for long-term durability on job sites, in manufacturing facilities, and across commercial properties. The self-closing design automatically returns the lid to a closed position after the device is used, helping keep the enclosed receptacle or switch shielded from the elements at all times, not just when someone remembers to close it manually.

Key Features

  • 1-Gang Configuration: Sized to fit a standard single-gang device box, making it a straightforward fit for common receptacle and switch installations.
  • Durable Glass-Filled Thermoplastic Construction: The reinforced material resists impact, cracking, and weather exposure better than standard unfilled plastic covers, holding up to repeated use in harsh settings.
  • Industrial Grade Build: Designed to withstand the rigors of industrial, commercial, and heavy-use environments where lightweight residential covers would fail prematurely.
  • Self-Closing Lid Mechanism: The lid automatically closes over the device opening whenever it is not actively in use, adding a continuous layer of weather protection without relying on the end user to remember.
  • Weatherproof Protection: Helps shield the mounted device from rain, dust, dirt, and other outdoor elements whenever the cover is in its closed position.
  • Single-Gang Footprint: Compact profile keeps the installation neat while still providing full coverage over the device opening.

Why Leviton?

Leviton is a trusted name in electrical devices, known for engineering durable, code-conscious products for professional installers and facility managers alike. This glass-filled thermoplastic weatherproof cover reflects that standard, combining an industrial grade build with a self-closing design so contractors, electricians, and property managers can count on reliable, ongoing protection for single-gang devices installed in tough or exposed environments. Choosing a purpose-built cover like this one over a generic plastic plate helps extend the service life of the underlying receptacle or switch and supports a cleaner, more weather-resistant installation overall.

Leviton 7420-YL – Frequently Asked Questions

1) Will the Leviton 7420-YL weatherproof cover fit a standard single-gang outdoor box?
The 7420-YL is a 1-gang cover sized for a standard single-gang device box, so it drops onto common receptacle and switch openings without adapters.
2) What is the difference between a self-closing weatherproof cover and a standard flip-lid cover?
A standard flip lid stays open until someone pushes it shut. The 7420-YL lid returns to the closed position on its own once the device is no longer being used, so the receptacle or switch stays shielded from rain and dust even when a worker walks away. That matters on job sites and loading docks where the same outlet gets used dozens of times a day. It is not an in-use (bubble) cover, so it protects the device when closed, not while a cord is plugged in and the lid is propped open.
3) Is the Leviton 7420-YL tough enough for a warehouse or manufacturing floor, or is it a residential-duty cover?
Built to Industrial Grade, not residential. The body is glass-filled thermoplastic, which resists impact and cracking better than unfilled plastic covers, and Leviton lists it for manufacturing plants, warehouses, commercial properties, and temporary job-site power.
4) Can I use a thermoplastic weatherproof cover outdoors, or do I need a metal one?
Glass-filled thermoplastic is a corrosion-free choice for outdoor and wet-location device protection, which is exactly what the 7420-YL is intended for. Unlike a die-cast metal cover it will not rust or seize at the hinge in coastal or wash-down areas. Where the installation takes real physical abuse (vehicle traffic, tool strikes), a metal cover is the usual pick.
5) Does the Leviton 7420-YL cover a receptacle or a switch?
Either. Leviton lists it for single-gang receptacle and switch enclosures, so the same cover works over an outdoor outlet or a weather-exposed toggle.
6) I need to standardize outdoor covers across a property. Is one model enough here?
The Leviton industrial self-closing weatherproof cover is sold as a single configuration, model 7420-YL, with no finish or size options to pick between. For a property manager stocking spares that means one part number covers every single-gang outdoor opening on the site.
7) Where can I get the full Leviton spec sheet for the 7420-YL cover?
Leviton publishes technical information for the 7420-YL weatherproof cover at https://zensupply.com/content/pdf/leviton/technical-information-509a25.pdf, which is the document to hand a plan reviewer or attach to a submittal.
