Measuring for your ABS euro cylinder lock upgrade (click to enlarge image) How to install your ABS euro cylinder (click to enlarge image)

Measure from the centre of the cylinder screw fixing to the outer face of the handle, both on the internal and the external side of your door.

The first measurement required is for the internal part of the cylinder. Measure from the screw as indicated on the diagram to the edge of the cylinder. The cylinder sizes go up in 5mm increments. Repeat this step for the external part of the cylinder. It is recommended that the old cylinder is removed to take the measurements (if the old cylinder is flush with the door handles and not protruding any more than 10mm).

Example: My front door has a cylinder that measures from the centre of the screw towards the inside of house to the edge of the handle of 40mm and from the centre of the screw again to the outside of the house and to the edge of the handle of 50mm. This means I need a 40/50 size cylinder. 40mm Internal, 50mm External.
