Selecting construction and installation dimensions

This row of 46800 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. The handle moves the swinging bolt and extension bolts into the locked position; the key blocks handle operation.

The installation construction of Security-shutter leaf must match Nickel-plated bolt. Additional locking points use M8 threaded 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.
