Frequently Asked Questions
- Is this door closer suitable for fire doors?
Yes. This model is suitable for fire doors when installed in approved configurations. - Is the closing force adjustable?
No. This is a fixed power EN7 closer. - What is a common installation issue on large doors?
Incorrect arm geometry or mounting position can reduce the effective closing force and cause poor latching.
Additional Information
- EN7 closers are typically specified where door size, wind loading, or heavy traffic requires higher closing force.
- On external doors, correct backcheck adjustment helps reduce damage from sudden opening due to wind.
- Because this is fixed power, door suitability should be confirmed before ordering, especially on lighter internal doors.
