Red ALKO wear indicator.  

• The wear indicator is fitted to the front of the coupling handle and the red wear indicator is fitted to it.
• Please Note - on some heads you need to take a nick out of the back edge to slide it on and glue it to the head.
• This wear indicator is fitted to AK160, AK300, AKS1300, AKS3004 and other ALKO coupling heads.

How it works

If the wear indicator is green your towball is within the permitted range. If the indicator is red the towball is on it's lowest limit ( 49mm ) or less
