ERA and Eurospec Mortice Locks

ERA British Standard Mortice Locks are manufactured to conform to the BSI Specification for Thief Resistant Locks - BS3621:1998.

This standard was created by a Standards Committee comprising of representatives from the police, government departments, local authorities, architects, window and door manufacturers and lockmakers. It provides a reference for type-testing and certification of thief resistant locks.

Before the standard is awarded to a mechanical key operated lock, designed for fixing to hinged or sliding doors, it has to be passed by an independent panel of locksmith experts. Once a lock has been accredited with the BS3621:1998 standard, it is recognised as giving the maximum protection generally available to the majority of both domestic and commercial premises.
Many insurance companies recognise this and reduce premiums accordingly, whilst some will provide cover only if such locks are fitted.

For a lock to be awarded BS3621:1998 it has to achieve the following criteria;

• At least 1000 different key patterns (differs) and 999 different locks must be made before any key pattern can be used again.
• There must be at least 5 moveable levers used. If fewer than 9 levers are fitted there must be additional anti-picking precautions incorporated (such as false notching).
• If a key can be used on both sides of a door, both sides must offer equal security.
• Handles and knobs must not operate the bolt when deadlocked.
• Deadlocking must be effective before the key can be removed.
• The bolt must project not less than 14mm when locked.
• Both sides of the lock body must be protected by anti-drilling plates.
• Vulnerable fixing screws on all parts of the lock, cylinder and staple must be concealed or inoperable when the door is locked.
