Product features

This 120 mm lock cylinder is designed to meet the needs of mechanical locking on a hinged door.

The copper used for the body and core of the cylinder contributes to the stability of the mechanism and makes regular use more comfortable.

Installation and usage advice

Before purchase, it is recommended to check the total cylinder length required as well as the internal and external distribution of your lock. Measure the old cylinder from the centre of the screw hole to each end in order to confirm compatibility. Also check the thickness of the door, the possible presence of a security rose and the type of lock already installed.

When fitting, insert the cylinder into the lock case, align the cam with the mechanism, then secure the assembly with the screw provided for this purpose. To preserve the proper functioning of the barrel, avoid greasy lubricants and use maintenance suitable for lock cylinders. Regularly checking the alignment of the door and strike plate also helps to limit premature wear.
