For our chainsets we use tested 8mm long link chain in AISI316 (A4) and each leg of the chainset exceeds the requirements of EN959 with a breaking strain of 2500kg.
We DO NOT use weaker chain and expect both legs together to meet this requirement. This allows any point in the chain to be clipped as a fully rated belay
We batch test all chain before incorporating it in our products and it has a breaking strain of 58kN.
