The Aluminum Bar Mount is a CNC-machined aluminum hard mount with a reinforced Composite Matrix cradle that securely holds the Mega Drive, Deca Drive, and XL LED lights. It is designed for 31.8 mm bars, with the cradle designed to pivot 15 degrees of lateral adjustment to direct light where it is most needed. The hinged clamshell design provides a great grip that is ideal for large lights. A large thumb screw secures the AL mount to the bar without need of tools and can be tightened by hand or a 4mm hex key. Molded rubber shims add grip and fine tune fitting to undersized bars. Aluminum Bar Mounts are sold separately and are not included with the Mega Drive, Deca Drive, or XL LED lights kit.
