19-CC2  4" Standard RND  Gooseneck Cushion Coupler for 2 5/16" Ball

The CC2 is furnished drilled for use on trailers with a safety thru pin.  However the pin cannot be used because of the internal mechanism of the Cushion Coupler.  Instead of using the thru pin, the CC2 is furnished with an ingenious studded collar  to safely lock the unit in place. Will also work perfectly in trailers with two set bolts and no thru pin.
