Surface-mounted lock

Invisible safety

The Lince Supratronik 4940 TK high-security electronic surface-mounted lock with integrated alarm is the ideal solution for invisible and effective protection.
Features
  • Internal installation: additional security installed on the inside of the door, with nothing visible on the outside, ensuring total discretion.
  • How it works: the lock blocks the door from opening once the main lock has been forced.

  • Built-in alarm: 90 dB alarm activated if an attempt is made to force the lock.
  • Battery life: runs on 4 AAA batteries, giving a battery life of around 15 months with 10 cycles a day.
  • Universal compatibility: adaptable to any type of door (wood, PVC, aluminium, metal) and ideal for a variety of uses (plant rooms, flats, offices, vehicles, cellars, etc.).
