Belayer requires significantly less hand braking force to arrest a fall Lowering a heavier climber is much easier to control OHM is attached at the first bolt in the safety chain Should a lead climber fall at the first bolt, the OHM significantly reduces the risk of a possible ground fall Rope handling when belaying a lead climber not affected (no additional friction when paying out rope) Recommended weight difference (lead climber > belayer): 10 - 40 kg Minimum weight belayer: 40 kg For single ropes from 8.9 - 11 mm CE marking: CE 0123, Weight 470 g Edelrid OHM 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. Specifications: Far less holding force has to be applied in the event of a fall Lowering a heavier climber is much easier to control OHM is attached to the first anchor point in the safety chain In the event of a fall at the first anchor point, the OHM significantly reduces the risk of a possible ground fall Rope handling when belaying a lead climber is not affected (no additional friction when paying out rope) Recommended weight difference (lead climber > belayer): 10 - 40 kg Minimum weight belayer: 40 kg For single ropes with diameters of 8.4 - 11 mm Brand: Edelrid
