Similar to a super clamp, the 9.Solution Savior Clamp offers an extremely tight grip and can hold up to 66lbs worth of gear, yet weighs under 1 pound by itself. It can also mount to irregularly shaped, non-round objects like square poles. Includes a ⅜”-16 male thread and 2x ⅜”-16 female threads, as well as 2x ¼”-20 female threads.
