This mount is designed to work with our Supercraft light but can also work with original Mastercraft lights. It bolts on to almost any round sissy bar (9/16-5/8dia) in minutes with our simple clamp on mounting brackets. ZERO WELDING OR DRILLING NEEDED!!!! You also can bolt it directly on to our Pangea sissy bars and our weld on sissy bar brackets if you feel so inclined. Includes polished aluminum backer, two sissy bar clamps, and all the hardware needed to get you choppering! Light sold separately.
