The 7156 is constructed of bronze and stainless steel, providing a very strong clamp for providing mechanical feedback for autopilots, power follow-ups or any electronic positioning of the rudder. Note that the 7156 cannot be used as a tiller arm.
The 7156 is available for use with rudder stocks from 3/4" (19mm) to 4-1/2" (115mm), and is available in multiple configurations to allow for ease of adjustment and configuration.
