Mottura Art. 54797TBDR56 4-bolt lock with latch and additional lock for Euro cylinder (without overlays)

The Mottura 54797TBDR56 front door lock is a 4-bolt lock with a latch and an auxiliary lock for a Euro cylinder. It is mortise, dual-system, semi-dependent, with three-way locking. The body and cover are made of steel. When closing with a cylinder lock, the deadbolt hole is covered by a special lever - a "curtain", preventing manipulation with lock picks and complicating vandalism. The main deadbolt lock: Deadbolt - four steel deadbolts with a diameter of 18 mm, deadbolt protrusion - 40 mm, for four half-turns. Additional cylinder lock: One deadbolt with a diameter of 18 mm, deadbolt protrusion 20 mm. for two turns. Removing the keyhole and the handle backset (Backset) 63 mm. The latch can be unlocked with both the handle and the key. The lock can be right-handed or left-handed, this model is right-handed.

The Mottura 54797 lock is a combination lock. Combination locks (PLURISYSTEM) have two different types of locking, combined in one lock, providing reliable protection against burglary and break-ins: the upper lever mechanism provides the main force locking of the lock, the lower cylinder lock provides a control function. The lock provides dependent locking of both mechanisms: when the cylinder mechanism is locked, the upper key covers the shutter opening.

The Mottura 54797 mortise lock is equipped with new-generation keys with variable coding, which have independent left and right sides, since the distance between the opposite teeth changes from position to position. In this regard, the manipulation of the lock is significantly complicated: to determine the key coding, it is necessary to recreate the configurations of both sides of the key and decode the first and second turns; due to the asymmetry of the key sides, the number of code combinations increases many times over.

The Mottura 54797 lock is equipped with 6 levers, among which there are levers without springs. Also, the lever block is located closer to the inside of the lock, and the shank stand has a built-in carbide ball that prevents drilling. This circumstance significantly complicates the opening of the lock with pickaxes and other criminal methods. It is recommended to install a manganese plate for the lock and an armor plate for the cylinder mechanism.

Mottura lever locks have a special patented mechanism against pressing the bolts into the lock. The key set is supplied in individual packaging, in a set of 5 keys. The number of code combinations is 144,000.
