Ferno FDU Double Stop Descent Device
This double stop descent device from Ferno is ideal for emergency escape, personal rescue, rescue operations or specialised rope work as a friction control, double stop descending system.
The system gradually releases its load when the handle is moved towards the central position. The double stop mode locks should a panic grab happen but unlocks progressively when the handle is released.
The Ferno FDU is available with a friction rack for rescue loads (2 persons)
Extensively tested and certified to AS/NZS 4488.1:1997 with 11 mm rope.
