I've got a job tomorrow on a set of double doors going out of a gym. The doors each have Von Duprin 99 exit devices with the standard lever on the outside and a mortise cylinder that turns one complete turn to the right to lock the lever and one full turn to the left to unlock the lever, (standard function). I think this would make the exit devices the vertical rod type.
The customer says most of the time he can turn the key one turn clockwise to lock the door lever but when he tries to unlock the door by turning the key one full turn the other way it turns about 330 or so degrees and stops. This unlocks to door but he cant pull his key out because it wont turn all the way. He then has to turn the key back locking the door to remove the key. Any thoughts?
I'll be gone on a call for a few hours. Those suckers cost a lot. Hint: It's a school gym and the current exit devices have been there since 96.
Thanks Glen
