TO BEVEL LOCK LUBRICATION

  • 1. Loosen adjustment screws at top and bottom of case.
  • 2. Turn front to desired bevel.
  • 3. Re-tighten adjustment screws.

All locks come lubricated from the factory with a lithium based grease. We recommend, however, continued periodic lubrication of internal moving parts with a commercial quality grease. This can add years to the life of the lockset by reducing excessive wear. For more severe environments, lubrication should be applied more frequently.

  • 1. Push locking piece toward desired locked side.
  • 2. Check for proper operation before installation.
