Changing Locks

How to measure euro cylinder lock

If you are looking at changing locks in your UPVC or composite door, make sure you measure for the correct size of cylinder. If your cylinder sticks out from the handle more than 5mm, then this becomes a security risk.
You can measure your locks in a couple of different ways. The image above shows you how to measure the lock in the door. You can also remove your existing lock and measure from the centre of the cam (the middle section that turns with the key) to the edge of the lock, then the same again to the opposite edge. Or, simply take your existing lock along with you when you purchase your new one. Not forgetting to ensure your property is secure before you leave 😉👍
