HERMAN MILLER UM226 - UM427 [CHROME] 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. If you are unsure as to which core you need, please contact Customer Service for assistance.
