Not sure which size cylinder you need?

Euro cylinders are measured in two halves, separated by the central fixing screw. Take both measurements from your existing cylinder before ordering, and match them to the size listed above.

A — External side
Measure from the centre of the fixing screw to the outer edge of the cylinder on the side that faces outside your home. Common sizes are 30mm, 35mm, 40mm, or 45mm.

B — Internal side
Measure from the centre of the fixing screw to the outer edge of the cylinder on the side that faces inside your home. Common sizes are 30mm, 35mm, 40mm, 45mm, or 50mm.

Cylinders are typically described as A/B — for example, a 35/45 cylinder has 35mm on the external side and 45mm on the internal side. Get both measurements right and the cylinder will fit your door perfectly.

Still unsure? Send a photo of your existing cylinder to info@homesecureshop.co.uk and we'll match it for you — or call 0151 521 8089 to speak to our team.
