The ultra-technical rigid crampon, ideal for ice climbing.
Rambo 4 is part of the technical crampon family. It is totally rigid. It has a forged front point that can be replaced with a single screw. The forging allows a three-dimensional shape to improve both the penetration into the ice, without rebounds, and the support. The adjustment is convenient because it is also done by means of a single screw. The position of each point is designed to provide greater stability in all climbing positions and on all forms of ice. Equipped with the famous Grivel proactive Antibott system both on the front and on the back.

CertificationCertificationsThe main climbing gear certifications are CE and UIAA--and normally the UIAA creates the rules that the CE body also supports. When possible, we try to list all the certifications the product carries. To sell a climbing product in Europe, the device must be CE certified. There are no official requirements to sell climbing gear in the US. The UIAA certification is a voluntary process. Learn MoreRock and Ice Certifications Guide |

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
