How to Choose the Right Type
Type A: Select this if your door and door frame are not at the same level (recessed frame). Install on the same side as the door hinges, with the base positioned 10 cm from the door frame.
Type B: Select this if your door and door frame are at the same level (flush frame). Can be installed on either the front side or the closing side of the door, with the base 10 cm from the door frame.
Installation Tips
- Identify whether your door is Type A or Type B (see above).
- Mark and pre-drill mounting holes on the door and frame.
- Attach the closer body and arm bracket using the supplied screws.
- Adjust the speed screw to your preferred closing speed — turn clockwise to slow, counter-clockwise to speed up. Do not tighten fully or the mechanism will not function correctly.
