Frequently Asked Questions
What is the difference between cylinder size and overall length?
Euro cylinders are measured by their cylinder size — in this case 65mm — which is the industry-standard ordering dimension. The overall body length (85mm) is the full physical length of the cylinder including the cam. Always match the cylinder size to your lock case specification, not the overall length.
What is a knob euro cylinder vs a thumb turn cylinder?
A knob euro cylinder requires a key on both sides of the door to lock and unlock. A thumb turn cylinder has a key on one side and a thumb turn (no key needed) on the other. Knob cylinders are typically used where keyed access is required from both sides, such as on double-glazed doors or where a thumb turn would be a security risk.
What doors is this cylinder compatible with?
This euro profile cylinder fits standard euro profile lock cases, commonly found in timber, aluminium, and uPVC doors. Verify your lock case accepts a euro profile cylinder before ordering.
What backset does this cylinder suit?
Euro cylinders are not backset-specific — the cylinder size (65mm) must match the distance from the edge of the door to the centre of the keyhole. Measure this carefully before ordering, or contact Doors Direct for assistance.
Is this cylinder bump-resistant?
The BBL 65mm Knob Euro Cylinder features anti-pick pins for resistance against picking attacks. For bump resistance, contact our team to discuss upgraded security cylinder options.
Can I order multiple cylinders keyed alike?
Yes — this cylinder is available keyed alike, meaning multiple cylinders can be operated by the same key. Contact us for keyed-alike sets.
Is this cylinder suitable for exterior doors?
Yes. The rust-resistant springs make it suitable for exterior door applications in residential and light commercial settings.
