Very impressive project you have going on there, Maik. On Cleveland Fed door, the timelock is mounted dead center on the door and the combination locks are mounted down close to the floor on the inside of the door frame. One of these days I will get back there to repair the dial knob that was clipped off when making a video of the door. That will require pulling the heavy side cover plate on the remote control viewer, so pictures of the mechanism will be taken. Doug
