The PullRite #331709 Capture Plate is a required component of the SuperGlide 5th Wheel Towing System. This plate is attached to your trailer's skid plate. When you're hooked up into your SuperGlide hitch and ready to tow, it isolates the rotation of your trailer's king pin in the hitch. Movement and rotation is then transferred to the automatic cam action of your SuperGlide hitch, moving it away from the cab along its rails to prevent the trailer from contacting the cab of your truck. This specific Quick-Connect Capture Plate for your trailer's king pin box is designed for quick install and removal for your convenience.#331709 Quick-Connect Capture Plate is used with most models of 5th Airborne pin boxes that are 10-1/2" wide.
