BEBOBLY BB2073 50 Amp RV Outlet Box, NEMA 14-50R, Lockable Metal Enclosure

The BEBOBLY BB2073 is a metal RV power outlet box with a NEMA 14-50R receptacle rated for 125/250 volts. Its enclosed design gives a compatible RV cord a sheltered connection point at home or at a temporary hookup.

A swing cover and lockable closure help keep the receptacle covered when in use. The rainproof Type 3R enclosure is designed for outdoor installation, making the box a practical choice for a yard wall or another suitable hookup location.

With a 50 Amp connection, it is intended for RVs, campers and trailers, and is also described for use with an EV car. The single receptacle accepts a matching NEMA 14-50P plug.

What to know

The NEMA 14-50R format is the key compatibility detail: pair the outlet with a 50 Amp cord fitted with a NEMA 14-50P plug. The box is rated at 125/250 volts and has one receptacle, giving an RV or trailer a dedicated connection point rather than relying on an exposed standalone outlet. Its metal enclosure, swing cover and textured weatherproof coating are designed to protect the connection outdoors, including in rainy or snowy conditions.

A spring-loaded button and lock hole at the bottom let you secure the enclosure and help deter unauthorized use of the power connection. The lid is designed to close over an inserted cable, so the cord can remain connected while the outlet stays enclosed. For a home RV parking spot, that creates a tidy, fixed hookup, for other setups, the product is also intended for temporary connections.

Fit and sizing

The enclosure is designed to accommodate a large-handle RV plug or 6-gauge wire, with space for the lid to close over an inserted cable. Three interchangeable aperture gaskets—1/2", 3/4" and 1"—provide options for different wire sizes. The pre-drilled hole design avoids the need to drill a mounting hole, while the concentric knockouts at the bottom and sides offer wiring entry points. Knockouts are intended to be removed with a drill or hammer and a flat screwdriver.

Usage tips

Plan the mounting and wiring route around the outlet’s knockout positions, then use the aperture gasket that suits the cable. Terminals are marked to support wire identification during installation. The enclosure’s curved bottom opening is designed to make wiring access more convenient, and its oval shape helps reduce the chance of scratching hands while working around the box. Because this is a mains electrical installation, have the wiring completed in accordance with applicable electrical requirements.

Need an outdoor RV connection that can stay covered around the cord? The lockable enclosure brings the receptacle, cable entry and swing cover together in one box, so the hookup can remain organized at a home parking space or temporary site.

Is it worth it?

For RV owners setting up a dedicated 50 Amp connection, the BEBOBLY BB2073 combines a matching NEMA 14-50R receptacle with a rainproof, lockable metal enclosure. The cable clearance, interchangeable gaskets and multiple knockout locations support a more adaptable installation, while the covered design helps keep the connection enclosed outdoors. It’s a good fit if you need a fixed or temporary hookup for a compatible RV, camper or trailer and want the cord protected within a lockable outlet box.
