* Solid Boom Arm Assembly. The BC-800W boom arm is knurled and 12mm thick (almost 1/2 inch) for slip proof dependability and strength. Its 16" length is perfect for most applications. * Retractable Boom/Straight feature. The BC-800W serves double duty both as a traditional cymbal stand and a boom stand. With the arm inserted into the upper tilter section it functions as a four section straight cymbal stand for added height. Extending the arm horizontally turns the BC-800W into a three section boom stand. * Easy Adjustable Design. The BC-800W offers secure, quick, and easy boom-arm adjustments using our single wing-nut design. Simply place one hand on the solid boom arm assembly, while the other is free to grasp and loosen the wing-nut, adjust to desired position, and tighten for complete ease of use.
