The YD25L is the world's first dual action, self-latching, electronic deadbolting door lock. Designed to reduce door misalignment and rattle problems. The YD25L first 'captures' the door with a magnetic latch, then secures the door with its deadbolting lock pin. This dual action helps the lock align correctly with the strike plate allowing for consistent locking even on swing through doors. Hidden in door frames or surfaces mounted to glass doors with the aid of accessories, this unique lock offers something new to the market.

    • A premier solenoid drop bolt with all the features expected from a top-of-the-line product and a unique integrated magnetic latch designed to help correct door alignment issues and eliminate door rattle.


    • The narrow design of the YD25L makes it the ideal lock for thinner door frames and provides a completely concealed solution when morticed.


    • Reliable and durable, the YD25L has been tested and approved to offer continuous locking for over 1,000,000 cycles. This, coupled with a holding force of 10,000N, ensures long term security in high traffic environments.


    • Offering feedback to the control panel of the door and bolt positions is a standard feature of the YD25L. Monitoring the position of the door and whether the bolt pin is extended or retracted provides vital information needed to ensure a site is safe and secure.

    Ideal use case

    Ideal for swing through doors that have small door alignment or door rattle issues. Widely used in commercial applications and very common on glass doors.

    Options and Accessories
    Model Comparison

    The YD25L has a built-in magnet latch, which helps ensure the correct positioning of the lock and strikes every time. Perfect for swing through doors, rattling doors, or misaligned doors.


    The durable design of the Solenoid Drop bolt range has made it one of the most reliable electromechanical locks in the world, rated at 1,000,000 cycles.

    High Security

    With a stainless-steel bolt pin, the YD25L has a holding force in excess of 10,000N. In addition, onboard control provides auto-relock and timed relock for added security.

    Complete Monitoring

    The YD25L can output both the bolt position and the door position as monitor signals. Monitoring the position of the door and whether the lock is open or closed, the YD25L will connect to your access control system to display the status of the lock for security.

    Low Current Consumption

    The YD25L will draw as little as 160mA holding current at 12VDC by utilising the built-in current reduction circuitry. Low current paired with high-security access control makes the YD25L a preferred product choice for many industry leaders.

    Integrated Access Control

    With factory-set fail safe and fail secure variants and multiple attempts to lock or unlock, the YD25L is ready for a wide range of application requirements. It can be integrated easily with access control or alarm systems.

    Versatile Installation

    The YD25L can be morticed flush into both the side, or top of many door frames. The lock is supplied with a matching strike plate as standard but additional items are available in the form of a housing and dress plate. These products allow the lock to be surface mounted when mortice installation isn't a preferred, or viable option. The housing and dress plates are supplied with self-adhesive tape for instant application to glass doors and door frames.
