StrongBOLT™ - the new BS lock from UNION
Strong, secure and highly resistant to attack, StrongBOLT™ is underpinned by the UNION brand reassurance of quality and performance.
- Unique chamfered bolt design significantly increases the performance of the lock under side load attack.
- Hardened steel roller pins within the bolt construction provide resistance from sawing.
- Shape of the bolt provides little opportunity for destructive tools to make positive contact.
- Easily and quickly retrofits into most UK mortices.
Engineered to meet the stringent BS 3621:2007 standard, the StrongBOLT™ mortice lock ‘ups the anti’ in high security locking.
