Selecting construction and installation dimensions

This row of 46825 has a fixed backset of 35 mm. Check the distance from the door-edge faceplate reference to the cylinder centre axis; overall case depth cannot substitute for it. In addition to the bolt and reversible latch, threaded-bushing connections are provided for additional locking points; the latch adjustment range is 11–17 mm.

The installation construction of Grille door must match Nickel-plated bolt and reversible latch. Additional locking points use threaded bushings; both accessory interfaces and installation positions must match.

The handle-to-cylinder centre distance is 85 mm; this and the 35 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.
