Double Mortise Replacement

Thanks for posting. If the locking teeth curve 'inward' toward one another, then it is possible mortise locks like the 82-239, 82-260 or 82-265 might be what you need. All three of these locks have the same body, just different faceplates. Compare with your old hardware and see if you think one of these match what you need.
