Euro Deadlock  

A euro deadlock is a specific type of cylinder lock that provides additional security to a door. It consists of a lock cylinder, typically operated by a key from the outside and a thumbturn from the inside, and a deadbolt that extends into the door frame when the lock is engaged.

The primary features and functions of a euro deadlock, also known as a euro cylinder deadlock or euro profile deadlock, are as follows:

1. Lock Cylinder: A euro deadlock incorporates a lock cylinder that is inserted into the door. The cylinder contains a keyway for inserting and turning the key to operate the lock.

2. Deadbolt: The euro deadlock includes a deadbolt that extends into the door frame when the lock is engaged. The deadbolt provides a high level of security by effectively securing the door against forced entry.

3. Key Operation: Euro deadlocks are typically operated using a key from the outside of the door. The key is inserted into the lock cylinder, which rotates the internal mechanism, causing the deadbolt to extend or retract.

4. Thumbturn or Key Operation: From the inside of the door, euro deadlocks often feature a thumbturn mechanism instead of a key. The thumbturn allows easy locking and unlocking of the deadbolt without requiring a key. In some cases, a key-operated mechanism may be present on both sides for added security.

5. Security and Protection: Euro deadlocks are designed to enhance the security of the door. When engaged, the deadbolt extends fully into the door frame, making it difficult for intruders to force the door open. This helps prevent unauthorized access and enhances overall security.

6. Compatibility and Versatility: Euro deadlocks are designed to fit into doors with a specific type of lock cylinder cut-out known as a euro profile. This standardization allows for easy installation and replacement, making them compatible with a wide range of doors.

7. Integration with Door Handles: Euro deadlocks often work in conjunction with separate door handles or knobs that control the latch mechanism. This allows for independent operation of the latch and the deadbolt, providing flexibility and convenience.

Euro deadlocks are commonly used on external doors of residential and commercial buildings, providing reliable security and peace of mind. Their compatibility, standardization, and combination of key and thumbturn operation make them a popular choice for door locking systems.

 

Sashlock 

A sashlock consists of a lock body that is morticed, or recessed, into the edge of the door. It includes a latch bolt and a deadbolt, both operated by a single lever or knob on the door handle. The latch bolt allows the door to be easily opened and closed, while the deadbolt provides additional security when fully extended.

The primary features and functions of a sashlock, also known as a mortice sashlock or mortise sashlock, are as follows:

1. Latching: The latch bolt is spring-loaded and keeps the door closed when it is engaged in the strike plate on the door frame. It allows for easy opening and closing of the door without requiring a key or additional action.

2. Deadlocking: The deadbolt is usually operated by turning a key or thumbturn on the door handle. When engaged, the deadbolt extends into the strike plate and provides a higher level of security, preventing the door from being opened even with physical force.

3. Key Operation: A sashlock typically requires a key to operate the deadbolt from the outside, providing additional control and security. From the inside, a turn knob or thumbturn is used to operate the latch and deadlock without a key, allowing for quick exit in case of emergency.

4. Privacy Function: Some Sashlocks have a privacy function that allows for locking the door from the inside without requiring a key. This feature is often used in bathroom or bedroom doors, providing privacy and convenience.

5. Handle Operation: Sashlocks are designed to work in conjunction with separate door handles or knobs. The handle operates the latch bolt, allowing the door to be opened and closed. When the sashlock is locked, the handle cannot retract the latch bolt unless the lock is unlocked using a key or thumbturn.

6. Security and Versatility: Sashlocks offer a higher level of security compared to standard latch-only locks. The deadbolt provides additional resistance against forced entry, enhancing the security of the door. Sashlocks are versatile and can be installed on various types of doors, including internal doors within residential and commercial buildings.

Sashlocks are widely used on internal doors within buildings, such as bedrooms, bathrooms, offices, or storage areas. They provide a combination of convenience and security, allowing for easy access while ensuring privacy and deterring unauthorized entry.
