Great connector, it is very well made. The best part it is made in USA and much better quality than other imported items. I had to buy as a replacement for another imported one that melted.High quality replacement 50A RV plug. Made in USA. Much better than the cheap, Chinese made replacement plugs. Highly recommend.Did the jobDecent plug. The design is OK. The screw gussets do not seem all that tough. The plastic is thin enough that you can't really trust dropping the cord. It seems fragile so I am careful setting it down. It's ok.Best plug on the market. Progressive is a stand up company. No cheap import product. Made in the USA and quality is outstandingThis is exactly what I was looking for to use with my welding machine extension cord.very prompt shipping and excellent quality
