Blocking system Edelrid Ohm (oasis)

Upstreamblocking system to increase rope friction in the event of a large weight difference between the climber and belayer. In the event of a fall, this device increases the friction of the rope, which allows a lighter belayer to hold a heavier leader without any problem .

• Much less force for the belayer to mobilize in case of a fall
• Much easier to control the descent of a heavier climber
• Fits on the first piton of the belay chain
• In the event of a fall from the first piton, the device reduces the risk of a possible fall to the ground
• No handling limitations for the lead climber (no friction when the belayer gives slack)
• Recommended weight difference (climber > belayer): 10 - 40 kg
• Minimum weight of belayer: 40 kg
• For single ropes 8.9 - 11.0 mm

• Approved rope diameter [mm]: 8.9 - 11
• CE marking: CE 0123
• country of origin: Germany
• weight: 470 g
