KABA MAUER - Boltwork Defender 720 - 83501

1- to 3-sided bolt work for safes CEN II-V.

The bolt work is protected by manganese steel plates. Tightening cords are used as additional protection. Due to two patented front shaft supports in form of integrated massive steel elements a very high manipulation protection is achieved. During the opening process the blocking is released by the forward motion of the shafts II and III. Afterwards the shaft I is drawn back.

No defined locking order in case of 2-lock operation.
