Each Pro-Mount aluminum roll bar clamps from Daystar is CNC'ed from 6061 aluminum for incredible durability. We use them for our Power Shot brackets, but they can be used to mount nearly anything such as action cameras, lights, or fire extinguishers. They will attach to almost any round tubing from 1.5 inches to 2.0 inches in diameter through the use of polyurethane shims. Without the shims, you can use the clamps on a 2.25-inch tube.
