A bolt-on kit for the 5GX has been provided in this package. For safety,
you MUST bolt the C5GX to your King Pin Box. Drill 1/2” holes to attach
the included bolts or if you wish to tap and thread the kingpin box: drill a
27/64 in. hole and use a 1/2 in. No. 13 tap to thread the holes. At least
one or two bolts are neccessary to prevent the adapter from turning on
the kingpin IN AN EXTREME SITUATION. There are 2 holes in the Adapter
Body Fins to attach the included Safety Chains. Always secure safety chains and lock the ball coupler
before operating. Follow the instructions on the reverse of this page to properly install the Positive Lock
