Backset and faceplate compatibility

Faceplate dimensions are 127×20×3 mm and backset E is 15 mm. E is the horizontal distance from the faceplate reference to the cylinder operating axis and cannot be replaced by door thickness; faceplate width and thickness must also match the door-edge mortice.

Operating construction and selection

The retracted deadbolt is flush with the faceplate; no separate latch or roller is included; Check fixing-hole positions separately for the 127 mm short faceplate and the 200 mm faceplate.

This model uses an oval-cylinder interface; a Euro-profile cylinder cannot replace it merely because the length matches. When installing the open lock case, prevent frame-machining debris from entering the mechanism.

Limitations

  • The diagram on this page explains only backset, not mounting hole positions; check the manufacturer's drawings for complete keep and connector dimensions.
  • Product dimensions and construction do not establish a security grade for the complete door or certification for a particular application.
