This deadbolt lock works on the basis of magnetism. When the door is closed, the latch bolt is pulled out by magnets causing the door to lock. The door is simply opened with the doorlever, but when it is open, the latch bolt no longer protrudes. This not only ensures a smooth finish, you also prevent damage to the frame or that you unexpectedly get stuck behind it. The backset of the lock is 50 mm and comes with a locking plate and front plate. The stainless steel brushed front plate has a size of 174 x 20 mm (hxw).
