Hamilton KB200M Universal Boom Clamp
A unique two-piece clamp will accommodate tubes from 1/2 to 1 inch in diameter. Positioning the clamp couldn't be easier thanks to the simplicity in separating the two clamp halves - one half is the clamp adjustment assembly and the other half houses the boom adjustment assembly. Long and short booms can be easily inserted, removed and adjusted (a full 360 degree circle) without losing the clamp position. The boom assembly will accommodate the two standard boom diameters of 1/2" and 5/8".
