Quantum Core is On-Stage Stands' first column-style keyboard stand. It is a pro level two tier stand with integrated cable management and fold-away captive support arms. Built around a rigid extruded aluminum core, the KS9102 is an extremely stable platform, capable of supporting 125lbs per tier; that's 250lbs total! Its four arms and three legs provide a broad foundation for instruments, yet fold neatly within the core for transportation. They are completely captive with no loose parts to lose. Whether deployed for performance or folded for transport, they stay attached.Each of the Quantum Core's two tiers is independently height adjustable. Overall tilt of the stand can be adjusted via a forth peg-leg to provide just the right playing angle. Strategically positioned cable clips accommodate instrument and power cables, resulting in a clean, organized presentation on stage. What's more, the central column features a combination 3/8" and 5/8" threaded adapter at its apex, fully compatible with any gooseneck or boom arm, eliminating the need for a microphone boom stand and allowing the cleanest possible keyboard setup.On-Stage Stands KS9102 Features:Column-style keyboard standIntegrated cable management2 tiers with independent height adjustmentCentral column features a combination 3/8" and 5/8" threaded adapter compatible with any gooseneck or boom arm4 Arms and 3 legs fold neatly within the core for transportation, no loose parts to loseOn-Stage Stands KS9102 Specifications:Weight Capacity: 125 lbs. per tier; 250 lbs. totalWeight: 17 lbs.Height Adj.: 10-44"Base Spread: 32" On-Stage KS9102 Column Keyboard Stand with 2nd Tier and Cable Management.
