Phil Webster wroteThanks for the replies. The stump is now as far up through the gates as it looks like it will go( above the green spot on pic) and i only see one stump. When i move stump up and down i see what appears to be part of the bolt sliding up and down in the keyway. Hope that makes sense. Doeas this help any?
Makes perfect sense - I am pretty sure that you have a dual control lock there …
I’ve just re-read your original post - yes I am 100 % sure that you have a dual control lock.
Have to got the 1st stage open ? (ie the bolt all the way up and levers at rest ?)
Can you see the 2nd stump ?
I can’t find a picture of the exact model you have, this lock does not have the multi stage thrower that yours does, although I have seen them like that and don’t recall any other major differences.
Given that the lock has the same footprint as the standard one why not drill for the boltwork / bolt interference point if you are having problems with the lock ?
