Fait enough. The one I saw couldn’t do what you have said. If there one that does then great.

That’s fair enough . What I saw didn’t have that facility and was useless but there are obviously different options available that can do a job.

I saw a first time lock user with a ratchet windlass. Not sure if it’s the same as you were looking at. The problem was the ratchet only worked one way at a time and had to be taken off what it was doing to change direction. It meant they couldn’t operate the mechanism locked one way to lift the paddle mechanism slightly to release the safety lock and then use it the other way under opposite lock to operate the paddle. Completely useless, unless I was missing something.
