The second generation of the innovative OHM is easier to use than ever thanks to a series of upgrades. The brake assist resistance to enhance braking power during team climbing on ropes with significant weight differences features a swivel joint that improves the device's freedom of movement. As a result, the direction of cut no longer matters when the device is attached to the first bolt. The locking system prevents accidental opening of the device and greatly facilitates inserting and removing the rope during descent.

• Much lower forces are exerted on the locking device
• Lowering a heavier person in a controlled manner is much easier
• The OHM II is attached to the first bolt of the safety chain
• The device reduces the risk of collision during a fall on the first bolt
• Handling the rope when securing a climber is unaffected
• Minimum locking device weight: 40 kg
• For single ropes from 8.9–11.0 mm
