Hey Norm… love the hitch mate beats the others I’ve had hands down. I’ve told a lot of people so hope it gets you some extra sales.
The Ratchet Hand Brake extension piece can be bolted onto the end of the existing brake ratchet. This will give you upto an additional 60mm of clearance for the hand brake. This will be particularly useful if you are mounting the hand brake on top of the main hitch body casting.
