Isnt the AK10/2 a standard ALKO non stabiliser hitch?
Virtually all of the locks sold should fit.
Not the stabiliser hitch ones though.
Insurance approved or thatcham approved?
Read the reviews before buying. I have a mechanical mind, Always working on cars and general DIY work.
Some locks seem to have obvious flaws in their design.
I have a Purpleline lock and it can be removed with a pair of long nose pliers. I know because i arrived at the storage without the keys/tools to remove it.
