【What's in the Box】1 electric A-frame jack, 3 flat and star washers, 1 manual crank handle, 1 level and 1 instruction manual. The red wire (+) connects to the 12 volt power supply.
【Durable & Sturdy】Made of heavy-duty steel, the electric A-frame trailer jack has a rated capacity of up to 3500 lbs. The outer tube has a durable exterior black powder coat, the inner tube is zinc coated, and the pedals are removable, providing good surface protection and greatly reducing the risk of rust.
【TerriFIC Function】Intended to be used with a trailer with an A-frame coupler by wiring to a 12 volt power supply. Maximum travel is 18 inches. The standard tube diameter for the Type A trailer jack is 1.5 inches and has a 14.25 inch drop leg travel. The four holes on the pedal bracket allow for height adjustment with fixing pins. Bright LED lights for night lighting.
【Time Saving】Just press the up switch to extend the jack until the pedal touches the ground. Push the switch down, minus the jack. The jack will slow down and stop as it approaches the fully retracted position. Release the switch at the first sign of slowing down. Do not shrink the jack beyond the STOP limit mark, otherwise damage to the jack may result.
【Emergency Operation】Manually override the crank in case of power loss. Unscrew the dust cap from the top of the jack. Insert the hand crank handle into the access hole and insert the drive screw. Turn the handle counterclockwise to extend the jack, clockwise to retract.
