abloy locks


All ENFORCER® ABLOY® locks are based on the unique operating principle of rotating detainer discs. Inside the

ABLOY® cylinder, a series of disc tumblers rotate and function like the tumblers in a safe. Only the correct key, turned 90 degrees will rotate the discs aligning the side bar gates. After davis-transfer-success-lock-2the discs are aligned to the correct opening combination, the locking bar drops into the aligned slot allowing the lock to open. To withdraw the key it must be turned in the reverse direction until it stops.  This will mechanically scramble the discs.    And as you can see from the picture . . . it is frustrating for the thief.   The will have to have a lot of time on their hand to beat this lock.
