  • Special, heavier wire for more fatigue strength and reliability

  • Anti-rotate feature to reduce stress on the inner wire

The most often replaced controls just got better!

High quality replacement knobs duplicate the original Piper color and shape to maintain the original factory appearance of the instrument panel. To select the correct knob for your aircraft, please see the Eligibility Chart.
