HexrackII clamps get a rock solid grip on the rails with a synthetic sleeve that fits between the clamp and the rail.
The Yamaha HexrackII Accessory Clamp is used for securing tubes of different thickness ("15 -"34, including hexagonal tubes) to an 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.
With a synthetic sleeve, HexRackII clamps get a rock solid grip on the rails. As the clamp tightens, it compresses the sleeve to establish a solid grip. This gives the clamp a secure, slip-free hold on the rail when tightened, and allows easy adjustment when loosened, making the whole setup process quick, easy, flexible and solid.
