The Karakoram Ultra Clip 2.0 with M5 Top Mount Hardware is the OEM standard in the splitboard industry these days, and it's no wonder. Karakoram's Active Joining concept revolutionized the industry when it was introduced, and tighter is still righter when you're trying to get your split to ride like your solid board. The Ultra Clip 2.0 is compatible with both top mount and through mount boards, but only top mount hardware is included here.
