Euro profile thumbturn cylinders offer key access from one side and a thumbturn from the other side of the door. They can be replaced easily in order to 'change the locks'
Measuring Euro Profile Cylinders
Euro Cylinders are measured in two halves from either side of the cylinder's 10mm centre section.
For Thumbturn Cylinders, the first measurement is of the side with the thumbturn.
Cylinders should be fitted so that they are flush with door furniture, particularly on the outside of the door.
