AL-KO AK 270 Ball Coupling Suitable for all common towing devices up to 2300 kg (with AL-KO up to 3000 kg) with horizontal or transverse holes. Safety display: If the green cylinder is visible in the coupled state, the coupling is correctly positioned on the trailer hitch of the towing vehicle. Wear indicator: An additional display on the coupling handle shows whether: A) the wear limit of the towing vehicle's ball hitch or B) the trailer hitch has been reached. Flat handle: The handle complies with the latest regulations and is very flat, so the tailgate can be opened without damage, even on towing vehicles with a low loading sill. Mounting: As with all AL-KO couplings, assembly is very simple. The old coupling is unscrewed and the new one is screwed on with two screws.
