Frequently Asked Questions

How do I measure a Security Cylinder Lock?

At DOM, we adhere to the standard industry method for measuring Security cylinder Locks. Start by measuring the exterior door thickness, followed by the interior. To accurately measure a cylinder lock, measure from the outer edge to the centre of the screw hole. This ensures a precise fit for your building's security system and ironmongery needs.

What is the difference between a 'Clutch' and 'Classroom' Security Cylinder Lock?

Clutch Security Cylinder Lock
A Clutch Security Cylinder Lock can always be overridden from the outside, ensuring emergency access when necessary. This feature is crucial for areas where rapid entry may be required, such as high-security spaces or environments needing quick responses to emergencies.

Classroom Security Cylinder Lock
A Classroom Security Cylinder Lock offers both security and safety in educational environments. It can always be overridden from the outside for emergency access but features a unique design: it cannot be locked from the inside using a thumb turn. This ensures controlled access while preventing unauthorized locking from the inside, providing additional safety for schools, colleges, and universities.

What is an 'Anti-Ligature' Security Cylinder Lock?

An Anti-Ligature Security Cylinder Lock is a specialised locking mechanism designed to prevent the use of the lock or its components for self-harm. These locks are essential in environments where safety and security are paramount, such as healthcare facilities, mental health institutions, and correctional facilities. By eliminating potential ligature points, these locks enhance security while prioritising the well-being of individuals in sensitive settings.
