I have a french door with a Yale Lockmaster lock. It isn't closing securely against the frame so is letting a draught in. It's the bottom roller cam that isn't holding the door against the frame. I tried adjusting the lower keep but it didn't help. Also adjusted the lower roller cam so that its as far right as it will go but that didn't help either.
The lower roller cam is very wobbly whereas the others don't move. I think the lower roller cam has been damaged by door slamming. Is there any way to tighten a roller cam? The allen key slot in the middle is for adjusting left and right but I don't see any way to tighten the cam. If I remove the whole mechanism is there a nut or something on the back of the cams that can be tightened?
