Martyn’s Law, introduced to improve security in public spaces, is prompting schools and other organisations to re-evaluate their locking strategies. With safety under greater scrutiny, it’s important for facility managers and school administrators to understand the options available and ensure their buildings are prepared.
Classroom vs Clutch Cylinders: What You Need to Know
With the introduction of Martyn’s Law, building locking strategies—particularly in education and public spaces—are coming under greater scrutiny. One area often overlooked is the difference between Classroom and Clutch lock functions.
In a barricade situation, a Clutch Cylinder allows a keyholder to override the internal thumbturn from outside, whilst still allowing the door to be locked from inside the room. This helps maintain control of the space while preventing unauthorised access.
Traditionally, many educational buildings have used Classroom Function, but in certain situations a Clutch Function may provide a more appropriate solution.
How Access2 Can Help
At Access2, we can help convert Classroom cylinders to Clutch Function without affecting the existing master key system. This means schools can upgrade their locking strategy quickly and efficiently, ready for the next term or planned refurbishment.
