UPVC French Widows - Lockmaster Lock
I fiddled about with the hinges today to improve the alignment a bit (one
door was rubbing the bottom lock plate).
I now find that I am having to pull up really hard on the handle in order to
get the key to turn. Everything appears to be well adjusted - the only thing
I haven't yet checked is if one of the hook bolts might be fouling the
bottom of one of the recesses in the opposite jamb.
Any obvious things to look out for? I took the Eurocylinder out and greased
the cam so it isn't friction in that area. The mechanism has 4 rollers and
two hook bolts as well as the normal shoot bolt operated by the key.
