AL-KO Profi AK 351 Trailer Coupling, 3500 kg, 60 mm, H16 + SafetyKit

Product detailed description

  The robust cast iron AL-KO AK 351 trailer coupling is a ball coupling designed for braked trailers with a maximum technically permissible weight of 3500 kg. It replaces the older AK 350 model. The package includes a protective Soft Dock bumper, a lock, a Safety Ball security insert and mounting hardware.

• The trailer ball coupling is equipped with a correct coupling indicator and a coupling wear indicator.

Package contents:

• 2x M16 hex-head bolts including nuts 
• 1x lock with two keys
• 1x Safety Ball security insert 

  The coupling does not require adjustment throughout its service life. Its mechanism compensates for wear on the contact surfaces of both the coupling and the towball. If excessive wear occurs, the side wear indicator points to the minus sign (-). In this condition, there is a risk of the trailer becoming detached from the towing vehicle, and the coupling must be replaced.

  If the indicator mark points to the plus sign (+), neither the coupling nor the towball is excessively worn, and the connection between the towing vehicle and the trailer is correct. The operating handle is secured by a push-button safety catch to prevent accidental opening. 

Important: Regular lubrication and cleaning will significantly extend the service life of the trailer ball coupling.
