ADI Block locks are Australian owned and made. They are installed on most commercial premises on the front doors as a secondary lock. They add a great deal of security to back up the main door lock such as a Lockwood mortise lock. You can tit ADI block locks to any door whether double or single door and is a great deterrent for any burglar.
JAB Locksmiths recommends the ADI Block locks to any commercial premises for extra security. We have installed block locks to many premises around Melbourne and surrounding suburbs, as the crime rate is increasing and the security needs to be upgraded to counteract the increasing crime. ADI makes a few versions of bolts including a 5004 ADI bolt and a slim line SL5 for sliding and hinged doors.
ADI is relevantly new product and made by a locksmith company in NSW and it has already taken off around the world as it is a very recognised product now.
JAB Locksmiths has installed an ADI Block locks to the front door of our premises and feel much safer knowing the block lock is on.
