Double Entry Cylinder
The double entry cylinder is the most popular system for securing entrance doors. This lock cylinder allows you to lock and unlock a door with a key from either side, providing versatile and reliable security. Unlike a knob cylinder, which isn’t ideal for glass doors, the double entry cylinder is suitable for a variety of door types and situations.
Choosing the Right Double Entry Cylinder
When selecting a double entry cylinder, consider the desired level of security, the thickness of your door, and whether it’s for an entrance or interior door. For entrance doors, a very high-security cylinder is recommended, while a medium-security cylinder may be sufficient for interior doors.
Measuring Your Double Entry Lock Cylinder
To determine the size of your double entry cylinder, measure from the center of the cylinder fixing screw hole to the edge of the door on each side. Thirard offers double entry cylinders ranging from 28x28mm to 40x60mm, ensuring a perfect fit for any door thickness.
Security Levels and Features
Thirard provides a wide range of double entry cylinders, from standard security to very high security. For entrance doors, a reversible key double entry cylinder is often recommended for ease of use. A declutchable double entry cylinder allows you to lock or unlock the door even if a key is already inserted on the opposite side, adding extra convenience.
Keyed Alike Options
Double entry cylinders can be customized to work with a single key for multiple locks, known as a keyed alike or single key configuration. This system allows you to use one key for your entire home, from the front door to the gate and mailbox, simplifying your security management.
