EXIDOR 3470 Electro-Magnetic Floor Spring (Body Only)

The Exidor 3470 electro magnetic floor spring is ideal for use in hotel and hospital corridors, where doors need to be held in normal use. The hold open function can be linked to the building's fire alarm system to release and close the door when the alarm is activated, by cutting the power to the spring. The 3740 is supplied body only and is CE marked and Certifire approved.
