"We all love the comfort and versatility of the Daisy-chain. But in its traditional version it can lead to wrong uses and become therefore dangerous. In fact no DC on the market is guaranteed to the CE values of 22kN, like the quick draws or the carabiners.
Therefore it can be the “weak ring” of the system, mainly when used in belaying. The pockets of a classical daisy chain have a very low loading strength which never exceeds the 2kN because they are designed for static load only, and consequently the only safe way to use a daisy chain as a sling is between the two end loops.
The Dyneema sling is so thin that can cut itself when in traction. Grivel has studied the problem over a long period of time, and has come up with the problem solving GDC. Today Grivel can offer a chain guaranteed to 22kN in every loop and every point! No more possibility of error, and no risk of mistake or dangerous manoeuvres.Also available with K1N carabiner."
