Description

The CURT X5 Gooseneck-to-5th-Wheel Adapter Plate with Square Shank (MPN 16310) converts B&W gooseneck hitches into industry-standard 5th wheel base rails, allowing use of 5th wheel hitches and rollers up to 20,000 lbs GTW. It features a square shank for gooseneck hitches with a square ball hole. Installation is tool-free: it drops into the gooseneck trailer ball hole and secures with the hitch's locking mechanism. It's protected by a durable carbide powder coat finish and a rust-resistant liquid A-coat.
