This is the same quick-release hitch pin included with EZ-Up weight bags and stake kits, but it can also have many other uses around the paddock and trailer.
The 1/4" diameter plated steel pin is a great choice wherever a secured quick-release pin is needed, but the precision and strength of a Pip Pin would be overkill. Great for securing a folding tire rack in the folded position, keeping the trailer hitch from coming unlatched, even securing the handle in your quick-lift jack. Pin diameter 0.25". Grip length 2.5". Sold individually.
