Frequently Asked Questions | FAQs
Are thumb turn locks safe to use on external doors?
Yes, but placement matters. A thumb turn lock is highly recommended for main exit doors (like front doors or communal flat doors) because it allows for a rapid, keyless exit in the event of a fire. However, they should not be installed on doors with single-glazed glass panels near the lock, as an intruder could break the glass, reach through, and simply turn the knob to gain entry.
How does a bathroom thumb turn lock work?
A bathroom thumb turn lock (often paired with a tubular mortice bathroom latch) provides simple, keyless privacy. You twist the thumbturn on the inside of the bathroom to throw the deadbolt. On the outside of the door, there is a circular release slot. In an emergency, this slot can be turned using a coin or a flathead screwdriver to unlock the door from the outside, ensuring safety if someone slips or gets stuck inside.
How do I measure a Euro cylinder thumb turn lock?
To ensure your new thumb turn lock fits perfectly, you need to measure your existing cylinder. Remove the cylinder fixing screw from the edge of the door and slide the cylinder out. Measure from one end of the cylinder to the centre of the rotating cam (the middle screw hole), and then from the centre of the cam to the other end. This will give you a dual measurement (e.g., 35-45mm). Always ensure the thumbturn knob is on the correct internal side when refitting.
