Measure from the centre screw — takes 20 seconds. We'll tell you the exact size to order.
A thumb turn cylinder uses a key on the outside and a small twist knob on the inside, so the door unlocks from inside without a key. They're popular for family homes, rentals and HMOs where quick escape in an emergency matters more than anything else.
They're safe when positioned sensibly. Avoid a thumb turn where an intruder could reach it through a letterbox, cat flap or by breaking a small pane — in those layouts choose key both sides instead. On solid doors away from glazing, a TS007 3-Star thumb turn offers excellent security plus easy escape.
Fire risk assessments for rented properties and HMOs commonly require occupants to escape without a key. A thumb turn satisfies that requirement while keeping keyed security on the outside — which is why letting agents and councils frequently specify them.
Measure exactly as a standard cylinder — centre of the fixing hole to each end — but note which side the turn goes. Sizes are quoted with the thumb turn side identified (for example 40/50T), so double-check the inside measurement matches the turn side when ordering.
