Tama's MC62 Double Multiclamp quickly and easily connects two down-tubes from almost any cymbal or tom stand out there! Combined with an extra tom or cymbal arm, and you can hold more instruments without carting around extra stands.
Using the FastClamp system you can just squeeze one side of the jaw (like a clothespin), clamp it onto your stand, and then do the same to the other side! Just a few turns of the tightening knob will finish the job.
Each clamp can fit a tube from 15.9mm to 28.6mm in diameter.
