Welcome to KLS Group, your specialist on Safety Locking Products and Interlocks.


Presented in many countries and industrialized areas either directly or with a network of agents and resellers. KLS is your local partner for Safety Locking Products and Interlocks.

Nowadays, in modern industrial plants, we realize how important it is to install mechanisms which prevent false movements which put workers and machinery in danger. The global trend of contracting out site operations inevitably translates into the 'casualization’ of labor, which in turn leads to an increased risk of accidents through human error or deliberate violations. Well designed interlocking systems can mitigate these risks - either by eliminating error or by greatly inhibiting the potential for violations.

We are a global leader in key interlock applications. The key interlocking systems, we offer, utilize locks and keys for sequential control of equipment and machinery to ensure safe operation.

While 'car seals' or padlocks and chains provide a lock-off capability, they do not provide any control over the sequence of operations, nor do they assure or confirm the status of the equipment to which they are fixed. So, removing a key from a padlock ensures neither that the equipment is locked nor its ‘open/closed' or 'on/off' status. While a padlock and chain or ‘car seal’ may be suitable and sufficiently robust in low risk applications, they have virtually no mechanical integrity and are a minimal solution offering (at best) a visual restriction against unauthorized operation. Key interlock systems are always operator-friendly – they require no additional work effort from the operator than normal procedures would require and, most importantly, should never permit more than one key to be free at any one time. The message is, ‘keep it simple’.

KLS Group is dedicated to ensure the safety of people and to avoid faulty operations in every exploitation conditions and installations.
