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.
