The Fuhr 855 type 8 keywind is a latch and deadbolt single spindle multipoint, with 2 round bolts and 2 rollers. It is operated using the key which engages and disengages the locking points. Two full turns of the key are required to fully engage the locking points. Instead of a lever handle, a fixed pad is used on the outside of the door and the key used to operate the latch. From the inside, the latch can be operated using a lever handle. The latch and deadbolt are reversible. The tapered nose on the round bolt ensures ease of operation and aids weather seal compression, whilst the 20mm throw of the round bolt provides security.
