Description

This AL-KO 4-hole override coupling suits trailers with hydraulic brakes. As the tow vehicle slows, the sliding coupling mechanism operates the supplied 3/4-inch master cylinder to apply the trailer brakes.

It is the 2000kg, 3/4-inch master-cylinder version for a standard 50mm tow ball. Check the 184 x 54mm mounting pattern and 137mm ball-to-first-hole dimension against the drawbar before ordering.

Features

  • Hydraulic override braking action responds to tow-vehicle deceleration.
  • Supplied with 3/4-inch master cylinder and handbrake assembly.
  • Zinc-plated finish.
