Why closers matter

A closed door stops fire and smoke, keeps conditioned air in and keeps security doors latched. Every fire door needs a self-closing device; on accessible routes the opening force and closing speed must also meet the code.

الأسئلة المتكررة

Which side of the door does the closer go?

Regular arm mounts on the pull side; parallel arm mounts on the push side – preferred for exterior and corridor doors because it is less exposed to vandalism.
