Ohm Assisted Braking Resistor

The Ohm is installed at the first bolt of your route. When a fall occurs, the device engages to increase friction on the rope, which significantly reduces the force the belayer needs to hold the climber. It essentially acts as a buffer, making it much easier to catch a heavier partner without being pulled violently into the wall.

No, the Ohm is designed to be transparent during normal climbing. It does not add extra friction when you are paying out rope, so your handling remains smooth and unaffected while your partner is climbing.

The Ohm is specifically engineered for situations where the lead climber is 10 to 40 kg heavier than the belayer. Additionally, the belayer must weigh at least 40 kg for the device to function as intended.

The device is compatible with single ropes ranging from 8.9 mm to 11 mm in diameter. It is not designed for use with half or twin ropes.

No, the Ohm is an auxiliary device, not a replacement. You still need to use your standard belay device as usual; the Ohm is simply attached to the first bolt to assist with friction management.

Attaching the Ohm to the first bolt is critical because it minimizes the risk of a ground fall if the climber falls early in the route. By engaging the braking mechanism immediately at the start of the safety chain, it provides extra security where it is needed most.
