FUHR 855-3 2 Hook, 2 Roller Key-Operated 'Key-Wind' Multipoint Lock

This is the Type-3 Fuhr 855 multipoint lock.  Commonly named a 'wind up lock', the gearbox offers complete key-operation without the need for handles.  These are a common solution to putting access control on uPVC doors because the key operation allows you to use a strike release and remove the need for handles all together (which cause problems for electronic strike releases etc).

In essence, the key-wind operation allows you to control the full multipoint lock via your key.  So where you would normally use the handles to operate the locking points by lifting the handle, on this gearbox the key operates everything, no handles needed what so ever. 

A double turn of the key will engage all the roller cams, then a double turn the opposite way will return them all.  A further small turn of the key will then pull back the latch. 

With the central latch and deadbolt, accompanied by two hooks and two rollers (one of each at both ends of the locking strip); these provide a good level of security whilst still allowing that keywind operation; all on a standard 16mm rail for uPVC doors.
