Premium 20 Cylinder core, Symo, individual locking, keyed to differ

Cylinder removable core – with different key changes

Art. no. 210.45.600

  • Symo 3000 accessories
  • Symo is a modular cylinder core system from Häfele. Without tools and time-consuming installation, it provides maximum flexibility at minimum costs and effort.


    Due to the variety of components within the Symo system, all present and future applications can be covered – and all this with maximum freedom during planning and execution.


    All components of the Symo system can be combined as required and exchanged, modified or upgraded at any time.


    Locking plans can be modified easily, quickly and economically. Only the cylinder core is replaced (without tools), the lock - and therefore the piece of furniture - remains untouched.

    Rational furniture production

    Since the lock and the cylinder core are separated, the locks can be pre-mounted in the furniture and are fully functional through their protective caps. The protective caps can be replaced easily and without tools by the required cylinder core at any time. The furniture can therefore be produced independently from its future use and from the required locking plans, and can be equipped with the required locks. This allows rational mass-production. The individual locks can be integrated into the locking plan by inserting the cylinder cores at any time, even after the furniture has been set up.

    Inserting and removing cylinder cores without tools

    No tools are required for inserting and removing the cylinder cores, which can also be done at any time after the locks have been installed. The cylinder cores can only be inserted or removed with the lock in open position. The cylinder can be removed using a removal key.

    Maintain the cylinder cores every 6 month, but do not treat the cylinder cores with graphite!

    Flexibility and economic efficiency – at any time

    Previously, removals, changed locking plans and security requirements as well as lost keys were the weak points of every locking plan which always required time-consuming and costly modification measures. Symo provides maximum flexibility even years after completion. Simply replace the cylinder cores to adapt the furniture locking concept to changed requirements. No tools are required and the installation is fast and simple. Whatever the requirements are: Symo is prepared.


    Plate cylinder or pin tumbler cylinder?

    With the Symo locking system you can choose between plate cylinders and pin tumbler cylinders.

    One protective cap, several functions !



    The protective caps for the Symo locks not only protect the interior of the cylinder housing against dirt or damages during the construction phase, but also function as temporary construction keys that can be operated with a coin or screwdriver due to their design. After construction is completed, the protective caps can be removed easily without tools and replaced by the required cylinder cores.

    • The subdivision of the required space is specified in height units (HE). In System 32 a height unit corresponds to 64 mm.
    • For card index boxes that are placed in the drop‐in bottom, the panel heights for the respective card index supports apply.
    • A gap of 3 mm has been deducted from the dimensions with the fixed lock panel and with the extending panel with lock.
    • Height units = HE are planning dimensions without gap.
