Installation and usage advice

Before purchase, it is recommended to measure the existing cylinder precisely in order to confirm that the 70 mm length is suitable for your door and your lock. It is also important to check the position of the fixing screw and the type of compatible lock. An incorrect measurement may result in the cylinder protruding or, on the contrary, insufficient fitting.

During installation, make sure to remove the old barrel carefully, then insert the new cylinder while respecting the alignment of the cam and the lock. Tighten the retaining screw without overdoing it to avoid putting stress on the mechanism. To extend its service life, it is advisable to keep the lock clean and use a lubricant suitable for cylinders if necessary. Avoid overly greasy oils, which can trap dust and disrupt operation.

This product is intended for use on compatible doors. For a door subject to specific security requirements, it is advisable to check whether the protection level of the cylinder is suitable for the intended use.
