This is a 50 ft, 50 amp RV extension cord built from 6/3+8/1 AWG pure copper STW wire, rated 250V and 12,500W, with a NEMA 14-50P male plug and a locking SS2-50R female connector. A 30A TT-30P to 14-50R adapter is included so the cord can run from a 30 amp campground pedestal. The locking ring on the female end resists pull-out from wind and vibration, which is the main thing it offers over plain non-locking cords. It suits large rigs and 50 amp setups that need a long run to the pedestal; the trade-off is weight, since the copper build makes it heavy to coil and carry.

This is a 50-foot, 50 Amp RV extension cord rated for 250V and 12500W. It uses 6/3+8/1 AWG pure copper wire with a PVC jacket. The male end is a NEMA 14-50P plug. The female end is a NEMA SS2-50R locking connector, which helps keep the connection from coming loose due to wind, vibration, or movement.
The male 14-50P plug connects to a campground power source, a generator, or a 14-50P outlet box. The locking female end accepts an RV, trailer, camper, or generator with an SS2-50R plug. Two adapters are included: a 30 Amp NEMA TT-30P male adapter and a 50 Amp NEMA 14-50R female adapter. With the 30 Amp adapter, the cord can connect to TT-30 outlets.
The adapter's copper pins are built for strong conductivity with minimal energy loss and no excessive heat buildup under prolonged high loads. Its PVC housing resists corrosion, dust, moisture, and impact. The cord is intended for 50 Amp, 250V RVs, travel trailers, fifth wheels, and other equipment of the same rating.
