The Edelrid Ohm provides an innovative solution for climbers that outweigh their belay partner, helping reduce risk to both people.  Climbers have the reassurance that their partner can control their fall, and belayers can avoid hurtling into the wall if they are pulled off the ground.

*Designed for a climbing team with a 22-88 lb (10-40 kg) weight difference. Suitable for 8.9-11 mm ropes.

The Ohm is an assisted-braking resistor installed in the safety chain of the first bolt.  When a fall occurs, the Ohm will increase rope friction allowing a lighter belayer to hold a heavier partner with greater ease.

The Ohm still allows for smooth slack payout and take-in of rope.  The Ohm is suitable for gym use and outdoor climbing.


  • 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 - 11.0 mm


  • Approved rope diameter [mm]: 8,9 - 11
  • CE marking: CE 0123
  • country of origin: Germany
  • Weight: 470 g
