Green pin certified shackles are much stronger than standard galvanised shackles due to a narrower jaw width and thicker pin diameter. Each shackle is supplied with a certificate of conformity. Unlike standard galvanised shackles, use the same size as the chain (because the pin is one size larger):
5mm = Proof Load 0.6 ton - WLL 0.33 ton - for 6mm chain
7mm = Proof load 1 ton - WLL 0.5 ton - for 7mm chain.
9mm = Proof load 1.5 ton - WLL 0.75 ton - for 8mm chain.
10mm = Proof load 2 ton - WLL 1 ton - for 10mm chain
11mm = Proof load 3 ton - WLL 1.5 ton - for 10/12mm chain
13mm = Proof load 4 ton - WLL 2 ton - for 13/14mm chain
16mm = Proof load 6.5 ton - WLL 3.25 ton - for ground chain
19mm = Proof load 9.5 ton - WLL 4.75 ton - for ground chain
