Anchor Chains vs Daisy Chains
Anchor chains were developed to address the growing misuse of daisy chains. The daisy chain is a closed loop of webbing with small loops made by bartacking either side of the webbing together at intervals along the length, one side of the webbing being offset to form the loops.
Daisy chains have an ultimate strength rating of 22kN, which depends on the stitching joining the ends of the webbing, but the catch is that when attaching to loops midway along the length, the intermediate bartacks will start pulling at about 3kN, because the strength of the loop depends on individual bartacks.
The other two bartacks in the group of three holding the loop don’t add to the strength of the loop because they are pulled out one at a time. However there is still an ultimate strength of 22kN.
A serious risk associated with daisy chains is clipping the carabiner into two loops either side by side or an end loop and loop further up. Failure of the loop stitching then causes the carabiner to become free.
Anchor chains are independent loops each rated to full strength, so attaching anywhere along the chain or through multiple loops results in a secure connection.
