Neoprene rubber "Pro" hitch. Has I-beam shaped metal pushed thru slots in material to hold closed. This hitch is a little more difficult than some to open, but we've heard that if you do it enough you can get good at getting them open quickly. Customers say this hitch tends to do less damage to a leg if left on the same leg for extended periods of time. Long lasting hitch, could go as long as 3-4 years on many farms. We use a nylon washer between the rivet crimp cap and the hitch for extra security, as there is no brass grommet in the hitch.
