Camco 50A to 50A Locking Power Grip Series

Camco 55552 Power Grip 18-Inch Dogbone Adapter -- 50A Male x 50A Locking Female

Bridge the gap between your RV's standard 50-amp power cord and a locking-style 50-amp shore power pedestal. The Camco 55552 delivers a secure, weatherproof connection with ergonomic Power Grip handles, a threaded locking ring, and flame-retardant PVC construction built for outdoor use.

The Right Adapter for Locking 50A Pedestals

Not every campground pedestal uses the same connector standard. Some sites -- particularly those in RV parks, state park hookups, and marina facilities -- feature a locking-style 50-amp receptacle that won't accept a standard 50-amp plug without an adapter. The Camco 55552 solves this directly.

It's a short 18-inch "dogbone" cord with a standard NEMA 14-50P male plug on one end and a CS6365 locking 50-amp female connector on the other. Plug the male end into your RV's power cord or power inlet, thread the locking ring onto the pedestal receptacle, and you have a secure, weatherproof 50-amp connection with no current reduction or step-down conversion.

Power Grip Handles

Oversized, ergonomic handle design makes plugging and unplugging easy even in tight spaces or with wet hands -- no struggling with flush-mounted plugs.

Threaded Locking Ring

The female end features a threaded collar that threads onto the pedestal receptacle, locking the connection against accidental pull-out and reducing moisture intrusion.

Flame-Retardant PVC

Heavy-duty, heat-resistant, flame-retardant PVC jacket resists outdoor UV exposure, abrasion, and heat buildup -- rated for continuous 50-amp load service.

Full 50-Amp Capacity

This is a same-amperage adapter -- 50A to 50A -- with no step-down. It passes the full 50A/125/250V service your RV requires for slide-outs, AC units, and high-draw appliances.

Full Power -- No Derating

Because this adapter connects 50A to 50A (not 30A to 50A), there is no current reduction. Your RV receives the full 50-amp service available at the pedestal -- critical for rigs running dual air conditioners, electric water heaters, or large inverter systems simultaneously.

What Is a Dogbone Adapter?

A "dogbone" is a short flexible power adapter cord -- typically 12 to 18 inches -- with a plug on each end. The shape and name come from the wider plug heads at each end and the narrow cord in between. Unlike rigid plug-on adapters, dogbones give you a short flex length that relieves stress on both the RV inlet and the pedestal receptacle.

Connector Standards Explained

The male end of the 55552 is a standard NEMA 14-50P plug (4-prong, 50A/125-250V), which mates with your RV's 50-amp power cord or inlet. The female end is a CS6365-style locking connector (50A, 125/250V), designed to thread onto the twist-lock receptacles found at many campground pedestals and shore power stations.

Storage and Maintenance Tips

  • Store the adapter coiled loosely -- avoid tight bends at the plug ends that can stress the cord jacket over time.
  • Inspect the locking ring threads before each use. Dirty or damaged threads can prevent a secure connection at the pedestal.
  • Wipe contacts dry before plugging in after rain. The locking ring adds weather resistance but is not submersion-rated.
  • Check for any discoloration or heat marks on the plug blades after extended use -- a sign of a loose or corroded pedestal receptacle that needs service.

Frequently Used With

  • Camco Power Grip 50A extension cord (50 ft or 25 ft) -- extend reach from pedestal to RV inlet
  • Camco PowerGrip inline surge protectors (50A) -- add surge and EMS protection at the pedestal before the adapter
  • Camco 55255 or 55215 -- 30A dogbone adapters for mixed-service campgrounds where 30A sites are also present

Important Information

  • This adapter is rated for 50-amp continuous service only -- do not use with 30-amp RV inlets or 30-amp pedestals.
  • Verify your campground pedestal uses a CS6364-style locking 50A receptacle before purchasing -- standard non-locking 50A pedestals do not require this adapter.
  • Always connect the adapter to the pedestal first, then plug your RV power cord into the adapter -- reduces arc risk at the pedestal.
  • Do not use if plug blades, the locking ring collar, or cord jacket show damage, cracking, or heat discoloration.
  • This adapter does not provide surge protection or electrical management. Use a separate inline EMS/surge protector for full electrical protection.
  • Outdoor use rated -- not rated for submersion or continuous water exposure.
