The B&W Trailer Hitches 16,000-lb Patriot rail-mounted fifth wheel slider hitch is built to exacting specifications for smooth and virtually inaudible operation. Unlocking the slider hitch is made effortless, even on irregular terrain, via the locking mechanism’s gear-reduced cam ratio design, which gives the user mechanical advantage. The Patriot’s two, solid 1" tubular steel carriage rails are designed with sturdy center supports that prevent the rails from deforming or binding as a result of flexing under load. Hourglass-shaped rollers convey the carriage mechanism with fluid motion, regardless of topography. Once unlocked, the hitch is free to slide back into its maneuvering position and afterward, it glides up to its locked position just in front of the rear axle.
