The Yamaha Hexrack II Arm Clamp connects two different Hexrack tubes that are positioned far from each other - and they don't even have to be the same size. Each clamp has an inner synthetic sleeve to protect and grip the rails.As the clamp is tightened the inner sleeve for a slip-free hold, but adjustment is quick and easy adjustment once loosened.

Several clamps for securing tubes of different thickness (φ”15 –φ”34, including hexagonal tubes) are connected to the extended arm. These clamps can be used to secure tubes positioned far from each other. Each clamp has a gear joint, enabling fine angle adjustment.
