The design of the Ohm was underpinned with scientific research at the Institute of Mechanical Handling and Logistics (IFT), Stuttgart, Germany. It is an assisted braking resistor which is attached to the first bolt in the safety chain. In the event of a fall, the rope is pulled into the braking unit of the device and the fall is progressively arrested. This means the OHM does not brake the rope abruptly, but incrementally, so that the fall can be dynamically caught by the belayer. The OHM increases the friction in the safety chain, regardless of which belay device is used. This means the belayer has to apply considerably less manual force to the brake-side of the rope and is not suddenly pulled upwards or against the wall.

Description
Description
Edelrid Ohm II Assisted Braking Device Features:
- 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
Edelrid's innovation to compensate for significant difference in weight between climbing partners
Specs:
- Weight (g): 360
- Load Capacity (kN): 20
- Good for sport climbing, top rope and indoor climbing

Frequently asked questions
Frequently asked questions
How do you ship?
All the orders are shipped with Canada Post. We use their Expedited service which offers a tracking number and $100 insurance. Depending on your location, you can expect you parcel do take between 2 to 8 business days to get to you once shipped. Here's a rough estimate:
- Alberta and British-Columbia: 2-3 business days
- Sasakatchewan-Manitoba: 3-4 business days
- Ontario and Quebec: 6-8 business days
- Maritimes: 7-9 business days
If you are ordering from the USA, you can expect between 7 and 15 business days before you see your order. That is because sometimes, the duty clearance takes time to process.
Can I get my order faster?
Yes you can. If you want your order to ship faster, you can leave us a note when you do your purchase online. We will then get a quote from Canada Post and will contact you with the shipping costs. Please note that we are not responsible for shipping costs when you want it expedited. You will have to cover all the cost for this shipping method.
Do you ship internationally?
We can. If you live outside Canada or the United-States of America, you can send us an email with the item you would like buy and your full address and we can get a quote from different courriers. Once we have an idea of the shipping cost, we will confirm with you the amount and then, we can proceed with phone order.
