The V50 MODULAR profile double cylinder is ideal for front doors and protects the door against break-ins and unauthorised access. Thanks to the emergency and danger function, the door can be opened even if a key is already inside the lock. The modular design means that the profile cylinder can be extended by 100 mm on the modular side. Extensions of 5 to 50 mm are available (in 5 mm increments). The double cylinder has the keyed alike system no. 11 and comes with 3 corresponding keys included in the scope of supply. The keys have an extra-long shoulder so that they can be easily used together with a security escutcheon. The large key head makes the key easy to hold and use.
