As standard, cylinders with thumbturn are supplied with our smooth elliptical turn with a thumb slot. A range of alternative turns are available to order to allow you to complement specific hardware. The range of turns includes our standard and mini accessible turns which provide a ‘lever action’ to assist users with poor or weakened grip to operate the turn easily.
The classroom function is a clutch cylinder where the turn can only ‘Unlock’ the door. This is typically used in schools to prevent mischief by students locking doors.
NOTE: Dimensioning these cylinders is with the external side (key side) first followed by the inside (thumbturn side) dimension, with the size taken from the centre of the fixing hole to the face of the cylinder
