Selecting construction and installation dimensions
This row of 46803 has a fixed backset of 25 mm. Check the distance from the door-edge faceplate reference to the cylinder centre axis; overall case depth cannot substitute for it. Compared with the threaded-bushing version, this group uses quick-connect bushings; the extension-rod connection must match the lock body.
The installation construction of Security-shutter leaf must match Nickel-plated bolt. Additional locking points use quick-connect bushings; both accessory interfaces and installation positions must match.
The handle-to-cylinder centre distance is 85 mm; this and the 25 mm backset are installation dimensions in different directions. Check cylinder length and trim on both sides separately for the actual door.
Limitations
- The backset diagram only explains the measurement reference from the faceplate to the cylinder axis; it is not an outline, drilling or installation drawing.
- Check cylinders, extension rods, strikes and other accessories against the specific model; accessories listed in the catalogue as available on request are not standard equipment.
- Series certification or suitability does not establish that any complete door currently meets the corresponding grade.
