The Nemef Z1749/09/42 and Z1749/47/42 are heavy-duty multi-point locks tailored for steel doors. Requiring minimum preparation they are of an easy to construct modular design consisting of a European style central sashlock with a one-piece radius forend. The steel rods just simply click into place onto the sashlock and join the upper and lower hardened steel swing bolt deadlocks. The rods are secured either end by a screw that allows adjustment. The swing bolts have a one-piece radiused mild steel forend which is zinc plated. Standard rod length supplied is 629mm but longer rods are available.
- 24 x 235mm radiused forend to sashlock. - 24mm double throw steel deadbolt. - Galvanised steel case. - Meets the requirements of DIN 18250. - European style central sashlock with 72mm centres. - 65mm backset & 9mm follower.
The central lock case has a one-piece 9mm follower and the operation is like a standard lock. The latchbolt is withdrawn by lever handles from either side and/ or key from the outside. All deadbolts are operated simultaneously by cylinder key or thumbturn. This lock is handed so please specify either Fig 3 Left Hand Open Out or Fig 4 Right Hand Open Out when ordering. Strike plates are available but are supplied separately. If using lever handles with an 8mm spindle you will require a follower sleeve (ref ZSC02) to convert to 9mm.
