This is a must-have for light belayers!

Assisted-braking resistor to increase rope friction when there is a large weight difference between the 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. This can reduce ground-fall potential, and risk of belayer injury.

• Belayer requires significantly less hand braking force to arrest a fall, and lowering a heavier climber is much safer and 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 is not affected (no additional friction when paying out rope)
• Recommended weight difference (lead climber > belayer): 10 – 40 kg
• Minimum weight belayer: 40 kg
• “Makes the belayer 25 kg heavier”
• For single ropes from 8.9 – 11.0 mm
• Weight: 450 g
