The 9000 Series includes heavy-duty and lighter weight stands in straight and straight/boom models. Stands feature memory locks on the tube joints and the tripod leg assembly, plastic tube insulators, toothless tilters with TechLock®, large reset handles and cymbal seat adjustment. The Techlock® secondary drum key locking system is a design inspired by working drum techs. The feature, incorporated at all critical adjustment points on DW 9000 hardware, is a safe-guard against slippage due to vibration during transport or play. Plastic tube insulators inside the heavy gauge tubing are a necessity in recording situations to avoid rattling when drum mics are placed close to cymbal stands. Hinged memory locks are included at tube joints, cymbal arms and tripod leg assemblies to guarantee 100% repeatable, precise height settings every time. The patented Cymbal Seat Adjustment can be raised or lowered to quickly adjust cymbal movement as needed. It can then be locked in place to assure desired spacing. The Toothless Tilter with TechLock® allows for infinite adjustment and secure positioning.
