DC700 EN3-6 w/arm RS (2018)

Freewheel slide rail G795 is used in conjunction with the DC640 EMF electro-hydraulic door closer. Recommended for fire doors where a "free running" function is desired. "Freewheeling" means that there is no resistance (spring force) after the DC640 is connected to 24VDC. The door can now stand freely in all possible degrees without resistance, but always closes in the event of a power failure or fire alarm. DC640 must be connected to ABDL system. When mounting with sliding rails G795 and G195, the closing force is EN 2-4.
