An assisted-braking resistor to increase rope friction when there is a large weight difference between belayer and lead climber.

The second generation of our innovative and successful OHM is easier to use than ever thanks to a number of updates. The assisted-braking resistor for increasing the braking effect when climbing in rope teams with major weight differences has a swivel joint that improves the device’s freedom of movement. As a result, the clipping direction no longer matters when the device is clipped to the first bolt. The locking system prevents the device from opening accidentally and makes it far easier to insert the rope and remove the device when lowering.

- Far lower forces are exerted on the belayer.
- Lowering a heavier person in a controlled manner is far easier.
- OHM is attached at the first bolt in the safety chain.
- The device reduces the risk of a collision when falling on the first bolt.
- Rope handling when belaying a lead climber not affected (no additional friction when paying out rope).
- “Makes the belayer 25 kg heavier”.
- Minimum belayer weight: 40 kg.
- For single ropes from 8.9–11.0 mm.
