The mortise lock GSV-No. 4040 K is a precision-engineered locking solution specifically designed for doors operated with a bit key, featuring an integrated antivibration latch for enhanced stability and secure closure. Constructed entirely from high-quality brass, the lock combines excellent mechanical strength, corrosion resistance, and long-term durability, making it suitable for residential, commercial, and public applications.

The lock is designed for a backset of 40 or 50 mm with a handle distancing of 60 mm, allowing accurate installation into standard door constructions.

This mounting configuration minimizes lateral movement, resulting in a rattle-free, precise operation of the locking mechanism over time.

The integrated antivibration latch enhances the performance of the lock by preventing unintentional movement or rattling of the latch when the door is closed, ensuring a secure, quiet, and reliable engagement. This feature is particularly advantageous in environments with frequent door use or where vibration and movement may otherwise affect the door’s secure closure.

The lock is supplied without a strike plate, providing flexibility for adaptation to different door frames and installation scenarios. Two bit keys are included, allowing immediate and convenient operation.

Overall, the GSV-No. 4040 K mortise lock delivers a technically advanced, durable, and secure solution for bit key doors. Its combination of high-quality brass, antivibration latch, precise engineering, and flexible mounting makes it a reliable and long-lasting choice for both residential and commercial applications.
