About This Product
The B&W ISR Adapter 20K does the same rail-to-puck conversion at lighter capacity. Twenty thousand pounds. For trucks with Industry Standard Rails that want to run puck-style hitches.
The adapter creates puck mounting points on top of your existing rails. Gives you more hitch options without redoing your entire mounting setup.
Made in USA by B&W. Useful for trucks that came with ISR rails instead of OEM puck systems.
Verify your rail system is compatible before ordering.
