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. If you are unsure as to which core you need, please contact Customer Service for assistance.

If you do not see your lock code listed go to the shopping cart page and check availability by lock code.
