The klemheist and prusik are both friction hitches that grip a rope when loaded, but differ in symmetry. A prusik grips when pulled either direction; a klemheist is directional — gripping one way only — but slides more easily and can be tied with webbing. Climbers pick based on the job.
| Aspect | Klemheist | Prusik |
|---|---|---|
| Grip direction | One direction | Both directions |
| Material | Cord or webbing | Cord |
| Sliding | Easier | Harder |
| Releases under load | Easier | Hard |
| Best for | One-way loads, easy sliding | Symmetric loads, ascending |
Use a klemheist when…
- The load is one direction
- You want easy sliding
- You only have webbing
Use a prusik when…
- You need grip in either direction
- You're ascending a rope
- You want a classic, symmetric backup

Frequently asked questions
What's the difference between a klemheist and a prusik?
A prusik grips when pulled in either direction and is symmetrical; a klemheist grips only when pulled one way but slides more easily and can be tied with webbing as well as cord. Pick the klemheist for easy one-handed sliding in a known load direction.
Can you tie a klemheist with webbing?
Yes — that's one of its advantages over the prusik, which works best with cord. The klemheist holds well with a loop of webbing or cord, handy when you don't have a dedicated prusik loop.
Which direction does a klemheist grip?
It grips when loaded toward the end where the wraps are neatly stacked and the loop emerges, and slides when pushed from the other side. Because it's directional, tie it the right way round for the expected load.
