Thumb Turn Euro Cylinder Locks – Anti-Snap Thumbturn Cylinders
Which thumb turn cylinder do I need? A thumb turn has a key outside and a turn knob inside, so you can lock and unlock from indoors without a key. For a front or back door, choose a TS007 3 star anti-snap cylinder such as the Avocet ABS thumb turn (our recommendation) or the Yale Platinum thumb turn. Measure the inside from the centre fixing screw to where the knob starts, not to the end of the knob. Avoid a thumb turn anyone could reach through a letterbox, cat flap or glass.
