I have 50 of these couplers and decided to put five of them on the Internet to
see if any body was interested in them. We use them for our Bobcat; they help to
change machinery in a hurry. The ends are made of 1/2 inch brass which can be
adjusted: bigger or smaller or just taken off . This stainless steel coupler will not rust. They are
great for boats, campers, big trucks, etc. We use them in the winter for starting
trucks, so when one is plugged in, you can start all of them and save electricity.
