Strength and dependability are not issues with the Lectrotab stainless steel trim tab design. Lectrotab Kit W/ Rocker Switch XKAF9X18. This kit combines a precision-engineered actuator with a non-hydraulic, maintenance-free design to provide silent operation with no hydraulics. The device is corrosion-free, assures exact tab alignment, offers maximum lift force, and is self-contained for straightforward installation. The new flat rocker switch from Lectrotab has better sealing to prevent water infiltration and a recessed rocker to avoid damage. An "immediate stop" circuit prevents actuator overrun when controls are disengaged. Key Features: A continuous rolled and pinned hinge offers increased durability and avoids the need for welding. The upper ram seal is impervious to fouling and barnacle development. Utilizes internal pressure equalization system The internal braking device avoids unnecessary tab movement during forward and reverses the motion.
