Standard Trim Tab Actuator - 12V - 28 CableLectrotab trim tab actuators are precision-engineered to combine quiet operation with a non-hydraulic, maintenance-free design. The unit is corrosion-free, ensures very accurate tab positioning, provides maximum lift force, and is totally self-contained for easy installation. The actuator assembly is packaged in a non-metallic, permanently sealed housing. No components need to be installed inside the boat. Most importantly, unlike hydraulic trim tabs, there is no oil to leak out. The actuator incorporates either a standard or low-profile transom mounting bracket. Actuators come in 12 and 24 VDC with an 8-second recommended stroke time or a 4-second stroke time.Features: Actuator DC Voltage - 12V 28 Cable The upper ram seal location cannot be damaged due to a fouled ram or barnacle growth Utilizes an internal pressure equalization system Upgrades to the most popular hydraulic and electromechanical systems Internal brake system prevents unwanted tab movement when underway or backing down Quiet operation All actuators are fully load tested to push 1000 lbs of force Non-metallic external structure that cannot corrode and will not deteriorate in the sun or underwater Specifications: Model: A-BK-24 DC Voltage: 12VDC Stroke Length: 2.25/57mm Stroke Speed: 8 sec Distance from Bolt to Pin: 11.5/292mm Vertical Height (Typical Installation Fully Retracted):11.875/302mm Cable Length (Feet/Meter): 28/8.5m Upper Mounting Bracket: Standard Lower Mounting Bracket: Standard Use Actuator with Tabs: All Tabs *Sold as an Individual table.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; } Truck Freight: No Oversized: No
