Selecting construction and installation dimensions

This row of 56016 has a fixed backset of 70 mm. Check the distance from the door-edge faceplate reference to the cylinder centre axis; overall case depth cannot substitute for it. Case height 82 mm, prepared for additional locking points and fitted with M8 threaded bushings.

Check case height and backset separately; 82 mm is neither cylinder length nor door thickness. Select extension rods and floor strikes for additional locking points as required.

The cylinder for this series is purchased separately; check thickness on both door sides, escutcheons and the cylinder fixing method.

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.
