Edelrid – OHM



The Edelrid OHM is an assisted-braking resistor to increase rope friction when there is a large weight difference between belayer and lead climber. In the event of a fall, the OHM increases the amount of rope friction so that a lighter belayer can hold a heavier lead climber without difficulty.

With the OHM, more friction is added when there is a significant weight difference between the lead climber and belayer. The Edelrid OHM increases more control for the belayer. The OHM is attached at the first anchor point. Should the climber fall at the first bolt, the OHM’s increased friction will reduce the risk of a possible ground fall. Paying out rope is not affected as the climber continues. Edelrid weight difference recommendation for the OHM to operate correctly is between the range of 25 to 85 pounds. Suitable for 8.9 to 11 mm rope.

Great option for those learning to belay lead climbers.
