HERMAN MILLER UM226 - UM427 LOCK CORES & KEYS



NOTE: The Herman Miller UM226 - UM427 lock cores are different than the CompX Timberline UM226 - UM427 lock cores. The Herman Miller and CompX Timberline cores have different housings and have a different configuration on the back of the core - they also require different control keys to remove and install them.
