TESA cylinders are manufactured according to the most advanced production processes, offering an extremely secure high quality product and meeting the requirements the market demands in every different area.
TESA’s range of cylinders includes a great variety of profiles in every system.

TESA also offers the possibility of combining mechanical cylinders with access control systems.

Security
Ranging from the most basic to the highest security patented, restricted-key models, our cylinders have been equipped with the most advanced protection systems: spring loaded pins, antiremoval system, etc., as befits TESA’s position as the first European cylinder manufacturer. Our restricted key systems guarantee that no blank keys will be found in the market, thus ensuring protection against counterfeit keys.
Masterkeying capacity
All TESA systems can be master keyed. A masterkeying is a planned locking system in which the master key can open more than one cylinder, even if each cylinder has its own key. For offices, residential homes and plants of various sizes, masterkeying is the immediate solution that allows to establish an access control while reducing the number of keys that must be handled: security and comfort.
A wide range
We have classified our systems according to four standards:             - Type of key (dimple or sawn)             - Restricted key             - Degree of security             - Masterkeying capacity     The combination of such standards has created a peerless range in the market, covering every requisite in projects ranging from the residential to the institutional, from cost-efficient technical systems to high security patented systems, offering the distributor maximum profitability.
Guaranteed byTESA
TESA meets the most demanding European standards for architectural fittings, in which cylinders are very important components in terms of protection and personal safety. Specifically, the EN 1303 European standard establishes five degrees of security (fire resistance, security against breakage, number of combinations, durability and corrosion resistance) for cylinders, based on design requisites and on practice tests simulating an attack. The DIN standard specifies which standards must be met by cylinders in order to obtain masterkeying certifications. Other standards and certifications met by TESA’s cylinders are UL (USA), NEN (Holland) ands SS (Sweden).
