Yamaha HXDBII HexRack II Double Bass Clamp Attaches Two Horizontal Tubes to Vertical Tube for Double Bass Kits

The double bass is used to horizontally set two tubes at the same height -as in a double-bass configuration, Settings at various angles are possible when used with the clamp gear joint.

HEXRACKII clamps get a rock solid grip on the rails with a synthetic sleeve that fits between the clamp and the rail. 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.
