Only fits two off bran boards, I also had to knob out the holes on these boards in a direction that is easy to turn the outter pin part to keep the boards locked in.. they been on the truck better part of a year. They pop on and off with ease, also boards are cheap enough I don't lock it with a pad lock, so if the boards are stolen I'm out what $60 🤷♂️ It's a lot of money but gotta say so far so good. Great product. Always seeing it's sold out.
