Description
Measurement (T) is the thumb turn side
Offers resistance to drilling, picking, bumping push and pull actions to deter forced entry. These replacement cylinders are so easy to fit that any DIY novice can do it in minutes!
- Thumb-turn cylinders offer the ideal security solution. The door can be locked and unlocked from the inside without the use of a key but without diminishing the level of security. This type of lock is also ideal in case of fires. If you have locked your door and could not find the key to get out in case of an emergency, what would you do?
- Our added security thumb-turn locks will fit all uPVC doors. They can also fit to Aluminium, Patio and Composite doors. Once fitted you simply turn the knob at the end of the cylinder to lock or unlock your door from the inside, you will only need the key to lock your door from the outside. These types of cylinders are ideal for front or back doors as they can be used efficiently in an emergency. These can be used to replace existing thumb-turns or the standard euro cylinder.
- Cylinder comes with 3 keys as standard.
- These are the standard cylinders you will find on most properties in the UK.
* These cylinders are measured from each of the cylinder to the central fixing screw

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.
