Installation Tips (Installer-friendly)

2. Secure the closer body with 4 × M5 screws into steel, timber or aluminium frame.

3. Fit the slide channel to the door leaf, ensuring a 3 mm rail gap.

4. Adjust valve 1 (sweep) for general speed; valve 2 (latch) for the final 10°.

5. Cycle the door five times and re-adjust for a silent, firm close.

Always seal fixings with fire-rated mastic on FD30/FD60 door cores.

FAQs

Is Force 3 enough for high-traffic doors?
Yes—Force 3 suits most interior doors. For doors over 950 mm, select an EN 4 or 5 closer.

Can I fit the IS65 on an outward-opening fire door?
Absolutely. The unit is non-handed; just invert the template.

Does it have a delayed action?
The IS65 focuses on swift yet silent closure; if you need delay, look at the ISEO IS315.
