The HH915D features the same long footboard as our Speed Cobra
  Bass Drum Pedal. Its core design is based on the Iron Cobra
  Hi-Hat Stand, widely recognized as one of the best performing
  hi-hat stands in the world. The longer footboard offers footwork
  flexibility, added control and sensitivity. The latest innovation
  on this stand, the new "Quick-Set Clutch", allows hi-hat cymbals
  to be quickly attached and removed. The Hinge Guard Block on the
  footboard holds the bearing more evenly, minimizing stress and
  maximizing smoothness.
