General information
Features and applications
CFO pin. offset lift-off hinges (ELESA patent) have been designed to adjust possible misalignments between the door and the frame.
They can be mounted on doors which open on the right or on the left side. Each body of the hinge has a slot for fitting the pin: the opposite side can be closed with the supplied cover.
Special executions on request
Screw-covers in different RAL colours.
To choose the convenient type and the right number of hinges for your application, see the Guidelines.

Instructions of use
Assembly instructions
- Fit the hinge bodies with octagonal slot on the frame and the other two bodies with cylindrical slot on the door.
- Insert the pins with octagonal slot in the two bodies fitted on the frame by matching the indexes engraved on the pin and on the hinge.
- Mount the door by matching the hinge bodies on the pins.
Adjustment of the door
In case the door is off line with the frame, the inclination of the door can be adjusted by turning the octagonal slot of the pins clockwise or anticlockwise.
By turning the pin anticlockwise, the distance S increases (+0.5) while by turning the pin clockwise, it decreases (-0.5).
Off line adjustments
The pin has an octagonal slot which allows different positions for the adjustment of off line door (fig. 1-2-3-4). To have the door in line with the frame, it can be necessary to adjust the pins of both hinges.
Adjustment examples
If the door is off line on the bottom side
In order to have the door in line with the frame, turn the pin of hinge 1 anticlockwise by 45° or 90° and the pin of hinge 2 clockwise.
If the door is off line on the top side
In order to have the door in line with the frame, turn the pin of hinge 1 anticlockwise by 45° or 90° and the pin of hinge 2 clockwise.
