  • Higher level of security with SBS

    Additional security is never superfluous! SBS (Security Block System) is a mutual blocking of the two locking systems in order to increase the security of the door.

  • The Door Locks Itself!

    How often do you ask yourself if you lock your door? And how about letting this question in the past? This is possible thanks to the innovative EasyGo feature that automatically locks your door. Is not that great?

  • Unlocking with your finger is so easy!

    Do you imagine that you do not wear either keys or RFID cards, and your key is your own finger? Has the end of the searching in the bottomless handbag come? Yes.

    This model has just that - SolidTouch ID, the device that transmits the achievements of biometrics into the higher security level of your door. Fingerprint unlocking included in this model makes it exclusive, high-tech and extremely secure.

  • Yes, thermal insulation is important!

    We know that thermal insulation is important. That's why we take care of your maximum home comfort by completing this model with an Automatic High + 51 rubber threshold, which lowers when the door closes and seals the gap between the door and the floor, S Thermo + rubber seal, which is integrated in the wing and frame and mineral wool, which is located in the wing of your door. This magic combination gives the heat insulation that every home needs!


  • An additional level of security - this is the built-in sensor and alarm set that monitors the condition of both locks (mechanical and electromechanical), the position of the door (open or closed) and the presence of strong vibration (shock sensor). In case of unlawful unlocking - external interference (burglary) the alarm is activated and the siren signals. Shock sensor monitors for external interference, shock or strong vibration. In case of door control via Solid MobileKEY, the administrator will receive a message (SMS) that the alarm is triggered.

  • The special insulating material Akustic Pad is a soundproofing EPDM placed under the decorative panels of the door. It provides additional 27dB sound insulation and allows you to feel the pleasure of having no external noise.

  • 10 pin cartridge, with extremely high security and many possible combinations. The key has new ergonomic design. Thanks to the better grip, the key fits perfectly into the hand and makes its everyday use very easy.

    The cartridge combines several protections:

    • Anti-subtraction protection;
    • Bumping protection against opening;
    • Protection against drilling;

    Solid 10 is available in 5-key version /in nickel/.

  • Leave the question "Did I lock my door?" in the past, thanks to the automatic locking of the electromechanical lock. After closing the door, the electromechanical lock locks itself off after a certain interval of time (3 to 12 seconds, default 7 seconds). Once you tried - you would not give up on it!

  • A higher level of convenience! This is ElLatch - the unlocking and locking button on the inside of the door. The button is LED and shows the status of the electromechanical lock (unlocked or locked). When an electromechanical lock is locked, the button lights up, and when it is unlocked it does not light up.

  • In the cartridge lock, the seal is in the cartridge, which is an external element for the lock itself. The historically well-established design of the cartridge makes it mechanically vulnerable. In order to protect the cartridge from a mechanical attack, Solid 55 developed its own protection - ProBox. This is a reinforced steel box for interior mounting of the lock.
    The cartridge is protected from a massively toughened steel body with a ring sinking into a polished place in the steel box. This makes it virtually impossible to break the cartridge.
    ProBox is further reinforced with 4 mm of steel or a total of 7.2 mm steel in the lock area that protects the locking mechanism.

  • Are we thinking of emergency situations? YES! sBoard is a specially designed Decorative Plate (engraved with Solid 55), which is placed at the bottom of the door. Below this plate is a special plug for emergency locking of the electromechanical lock. Required element for all doors with hidden lock (electromechanical lock).

  • Additional security is never superfluous! SBS (Security Block System) is a mutual blocking of the two locking systems in order to increase the security of the door. When locking both locks, the mechanical lock locks the door unlocking by a RFID card or ElLatch (button). In order to open the door, we first unlock the mechanical lock and then we can now unlock the electromechanical lock with the card or ElLatch.

  • This is an innovative home security solution that combines mobile technology and the electromechanical lock system, with many new features:

    Unlock / lock the door remotely with a single tap on your phone;

    You decide who to give access to your home;

    You see when someone in your family is back home;

    You receive an alarm if someone tries to get into your apartment.

    A specially developed application for Android and iOS mobile phones through which you manage the Solid.Me features.

  • SolidTouch ID offers a high level of security in which the finger becomes a key. The lack of physical devices - keys, chips, RFID cards or access codes - prevents opponents from entering the door illegally. The combination of the highest class of biometric sensors with the unique locking mechanism eliminates any possibility of manipulation or malicious interference. To unlock the door, SolidTouch ID only needs to recognize the fingerprints. Sensors recognize finger relief and take into account more biometric factors such as heat and pulse to ensure home security. Issuing and removing access is through a specially developed mobile application and by storing the fingerprints that will unlock and lock the door.
