Enclosure for Harsh Environments

The VEVOR ST4420 is a NEMA 4X rated steel electrical box built for outdoor and indoor use. Its IP66 rating blocks dust and powerful water jets. The 1.5 mm cold-rolled steel body with epoxy polyester powder coating resists corrosion in factories, construction sites and residential courtyards. A lockable hinged door secures internal components.

Upgrade From Basic Junction Boxes

This enclosure replaces standard unsealed boxes when equipment must survive wash-downs, heavy dust or direct weather exposure. The jump is worth it when a project demands NEMA 1, 2, 4, 4X and 12 compliance in one unit. It is not suited for applications requiring transparent covers or non-metallic construction.

Straightforward Wall Mounting

The box ships with the 2 mm galvanised backplate already fitted and a set of wall mounting pendants included. Installers bolt the enclosure through the pendants, then populate the backplate before closing the hinged door. The foam sealing strip must sit clean and undamaged to maintain the IP66 seal; debris on the gasket is the most common cause of leaks.

Questions about this item

What size wall opening fits the 16 x 16 in outer dimensions and 13.8 x 13.8 in mounting plate?

The enclosure measures 16 x 16 x 8 in overall, with a 13.8 x 13.8 in detachable galvanized backplate that mounts inside the 15.6 x 15.6 x 6.6 in interior cavity.

How is the hinged door secured and what step is often missed during mounting?

The door uses a high-strength hinge and lockable latch; the included wall-mounting pendants must be fastened through the rear housing before the backplate is reinstalled.

When should the foam sealing strip and bottom sealing plate be inspected or replaced?

Check the foam strip and bottom plate annually or after any impact; replace them if compression set, tears, or corrosion appear to maintain the IP66 seal.
