Mortice Locks

A mortice sashlock combines a latch and deadbolt, fitting inside the door. Operated by a key and a door handle or other furniture, it provides a secure locking mechanism. 5 lever sashlocks are common for external doors, while 3 lever sashlocks are suited for internal doors. BS3621 mortice sashlocks meet insurance requirements, offering high security.

Mortice sash locks provide dual security with a latch and a deadbolt, making them ideal for wooden doors. The deadbolt is operated by turning the key, while the latch can be operated by a door handle. This allows for ease of use without compromising security. The number of levers determines the lock’s security level, with 5 lever sash locks typically used on external doors and 3 lever sashlocks on internal doors. For insurance compliance, ensure the sashlock meets BS3621 standards.

Mortice deadlocks feature only a deadbolt, which must be engaged with a key. These locks are often used alongside nightlatches on exterior wooden doors. 5 lever deadlocks are standard for external use, providing robust security, while 3 lever deadlocks are ideal for internal doors. Ensure compliance with BS3621 for insurance purposes.

Mortice dead locks are purely deadbolt mechanisms, ensuring maximum security when engaged. They do not require door furniture and are often paired with nightlatches for additional security. Historically, a Yale nightlatch combined with a Chubb mortice deadlock was a common installation for external doors. The security level of a deadlock depends on the number of levers, with 5 lever deadlocks being more secure and suitable for external doors, while 3 lever deadlocks are used internally. Compliance with BS3621 standards is recommended for enhanced security and insurance purposes.

Both mortice deadlocks and sashlocks can meet BS3621 standards, providing the highest level of security. These locks are often required by insurance companies for external wooden doors. They feature a bolt that throws at least 20mm and hardened plates to resist drilling.

BS3621 mortice locks represent the pinnacle of door security, meeting stringent British Standards. These locks, whether deadlocks or sashlocks, offer features like a bolt throw of at least 20mm and hardened plates to prevent drilling attacks. Upgrading to BS3621 compliant locks is often mandated by insurance companies for external wooden doors. These locks not only provide superior protection but also ensure compliance with insurance requirements, offering peace of mind to homeowners and businesses alike.

6 & 5 lever mortice locks offer similar features to BS3621 locks but are not insurance compliant. They are available as either sashlocks or deadlocks, providing a high level of security for various applications.

6 and 5 lever mortice locks are robust security solutions for various door types. While they share many features with BS3621 locks, they do not meet the same testing standards and are thus not compliant with insurance requirements. Available in both deadlock and sashlock variants, these locks provide substantial security for residential and commercial properties. They are suitable for those seeking high-quality locks without the necessity of insurance compliance.

Detainer locks, often by Union, use detainers instead of levers, offering superior security. These high-quality locks are ideal for situations requiring enhanced protection.

Commonly used for bedroom doors and other internal applications, these locks provide a balance of security and functionality. Available as both sashlocks and deadlocks, three-lever locks are a practical choice for internal doors. While they do not offer the same level of security as five or six-lever locks, they are sufficient for areas where lower security is acceptable.

2 lever locks, including rebated versions for double or French doors, are suitable for low-security internal applications. These locks are not designed to withstand significant attacks.

These locks are often used on internal doors that do not require substantial security, such as closets or storerooms. Rebated versions are available for double or French doors, providing a secure closure without needing high security. While not designed to withstand significant attacks, two-lever locks offer a basic level of security for non-critical areas.
