The Demco 6140 adapter converts a B&W-style ball mount so it fits a 21,000 lb-rated industry standard rail (ISR) system, giving you a way to change hitch brands without tearing out your existing bed rails. It's adjustable to work with bed liners.
This is a mounting adapter, not an automatic sliding hitch — it's not intended for use with slider-style 5th wheel hitches. Double-check manufacturer part numbers against your truck and hitch before ordering to confirm a proper fit.
Confirm compatible part numbers with the manufacturer before purchasing to make sure it matches your specific truck and hitch setup.
