Answers to Frequently Asked Questions about door dampers
Choosing the model
The spring force is influenced by the following factors:
- The required force to finally close the door left ajar
- The mounting position: The farther away from the hinges the door damper is fixed, the lower the required spring force is.
Measuring the required spring force:
In case the door damper is fixed at the closing edge of the door, the closing force of the door damper has to be higher than the hand force, i.e. the force required to close the ajar door by hand. This force can be measured using a spring balance/a balance for suitcases in the area of the door handle.
But you don’t have to determine the spring force on your own. Our customer service will be happy to help you with choosing the appropriate door damper – just contact us!
The large choice of DICTATOR door dampers provides many application possibilities. The models differ in the possible mounting positions and also in their appearance and finish.

* Pull side and push side of the door
** Position of the door in the frame
In case of overlapping doors, the door leaf is positioned in front of the frame; with flush doors, the door leaf is flush with the frame, and with recessed doors, the door leaf is behind the frame. You will find more details in “Which hook do I need?”
For the models V 1600, V 1600 F, Z 1000 and H 1300 three hooks with a different length each are available: 1009, 1011 and 1013. Which hook to choose depends on the position of the door leaf on the side where the door damper will be fixed in relation to the frame: flush, overlapping or recessed.
The hook 1009 is used for flush doors or those up to 4 mm behind or 14 mm in front of the frame.
The hook 1013 is used for doors which are 15 – 30 mm in front of the frame.
The hook 1011 is used for doors which are between 5 – 20 mm behind the frame.

Installing the door damper
DICTATOR offers door dampers for the pull side as well as the push side of doors.
Mounting on the pull side (side to which the door opens):
When doors open to the inside, the door damper is usually mounted on the inner side (pull side) (e.g. VS 2000, V 1600, H 1300).
Mounting position on the door:
The door damper is usually fixed vertically at the top-center of the door. The VS 2000 requires at least 65 mm for the hook above the upper edge of the door leaf, and the V 1600, at least 82 mm.
Should there not be enough space available (e.g. when the door leaf features a large glass panel or the space above the door is too little), certain models can be mounted in horizontally at the closing edge. In this case, you have to keep in mind that the closing force of the door damper becomes more efficient the farther away from the hinges it is fixed.
Mounting on the push side:
For this type of mounting the R 1400 door damper is used. It is fixed on the closing edge – either vertically or horizontally.
We’ll gladly assist you!
Should there not be sufficient space for the installation or should you have any further questions, please contact our technical customer service.
The closing speed of all DICTATOR door dampers can be adjusted, except our fire door damper V 1600F and the Junior. However, this influences the spring force and the closing force of the door damper only slightly.
To change the closing speed, turn the adjusting screw as shown in the picture.
If you have questions, please contact our technical customer service.
The special door damper for fire doors V 1600F may be used on approved fire and smoke doors or those for which a manufacturer’s declaration allows it. You will find all approved manufacturers and door models in the document List of fire doors with V 1600F. For all other door models we’ll be happy to find out for you if an individual approval is possible.
On many fire and smoke doors there are mounting plates prescribed for door damper and hook. Please check which mounting plate(s) you need for your door before ordering. You will find this information in the aforementioned document, too.
