Edelrid Ohm II

"The second generation of Edelrid's innovative and successful OHM, the OHM II, offers significant improvements to maximize usability and safety when climbing and bouldering. This device is installed in the first hook of the belay chain and ensures that the belayer has to withstand significantly less force. The initial resistance is particularly advantageous for rope teams with a large weight difference, as it increases the braking effect and makes lowering a heavier person more controllable. A swivel joint allows more freedom of movement so that the direction of insertion no longer plays a role."
"The OHM II is equipped with a reliable locking system that prevents accidental opening and makes it easier to insert and remove the rope when lowering. There are no restrictions on handling during lead climbing, as there is no additional rope friction when the rope is released. The device is suitable for single ropes with a diameter of 8.9 to 11.0 mm and increases the weight of the belayer by 25 kg. This significantly reduces the risk of a collision in the event of a fall into the first hook"
"To ensure safety, the person belaying should weigh at least 40 kg. The OHM II is therefore ideal for anyone who wants maximum safety and comfort when climbing and boulderingu00f6. Whether for sport climbing or bouldering, the OHM II from Edelrid is an indispensable aid that ensures greater safety and control"
