Security lock JNF IN.20.003 3-point, cylinder

The security lock JNF IN.20.003 is a mortise security lock for wooden doors with 3-point locking, made of stainless steel EN 1.4301.

The faceplate, the security bolts and the latch are made of stainless steel EN 1.4301 (AISI 304), and the faceplate has a brushed, satin finish. This construction provides greater security and rust resistance and extends the service life of the lock.

The lock bolts at three points over the height of the door leaf, which adds resistance and makes forced entry considerably harder. It is prepared for a profile cylinder, the backset is 60 mm and the centre distance 85 mm. The latch is reversible, so the lock is universal and fits both left- and right-hand doors.

The faceplate is 2030 mm long and all fitting dimensions are given on the drawing with the letters A–N. The pack contains the lock with its faceplate, three strike plates and screws; the cylinder and the handles are not included.
