Safetec Duck R

Primary functions

Cam pinches the rope when loaded from the connection point
Absorbs force in case of a fall by slipping until force is reduced to 3kN
Positioning cord allows device to be brought down on the rope and reduces the chance of defeating the device

Attach with EN lanyard up to 60cm long or knotted lanyards of dynamic rope 80cm max from ventral attachment, 50cm max from sternal attachment, including connectors
Pre-rig device by pushing cam through and clipping with a lanyard
Install on rope with arrow towards tensioned side of rope and allow cam to swing back through
Function check by moving device up the rope then pulling down on lanyard to ensure it locks down on the rope
At all times that the user is stationary the Duck-R should be positioned as high as possible. The Duck-R must always be above the descender or chest ascender and never below its lanyard/cows-tail attachment point (FF1)
To move the Duck-R up the rope, hold the lanyard or karabiner- do not hold the device
To move the Duck-R down, pull the Positioning cord down using the index finger and thumb. Users should only hold the positioning cord for as short a period as necessary and ensure that they are prepared to let go of the Positioning cord immediately at all times
To remove from the rope – disconnect the karabiner, pass the Cam through the body and re-connect the karabiner before pulling the device from the rope
In many applications the Duck-R should be controlled independently of the descent device (one for one technique) in others it may be necessary to control both Duck-R and descent device simultaneously
Slippage less than 3cm at 2.5kN
Slippage increases at FF1 and FF2, but does not exceed 50cm
Required clearance height- 2m plus rope stretch

On low angles, keep device high and to the side to reduce the chance of trapping device between surface and user
In windy conditions, add friction below device or anchor rope below so that slack does not develop
When working within 3m of knots, edges, or other obstructions, maintain the Duck as high as possible with less than 10cm slack in the lanyard

Device must be maintained above shoulder level of both rescuer and casualty
If practicable, one device should be used for each person, each on its own rope and controlled separately of the descender
More clearance required
Slippage of 150cm or greater at FF1 and FF2, with forces not exceeding 6kN

check for any corrosion, cracks, evidence of abrasion, deformation, loose bolt or missing components, including positioning cord
1.5mm max wear on friction point and inside body
10 years max life from first use
full function test
Lubricate cam and spring if needed
The positioning cord can be replaced with 4mm cord no longer than 40mm, or 3mm cord no longer than 50mm
