Choice of chain

specs of tensile strength for each chain.

3/8th duplex has a minimum tensile strength of 16946N

1/2 simplex has a minumum tensile strength of 13344N

depends on how much tourque your pulling.. i work with litrally miles of 1/2 duplex chain at work. Its not light stuff.

Toxic uses 1/2 chains, I have only ever had 1
problem...... when tiberius snapped one in two
when it got nipped quite a lot !!
At the same time tiberius put a 1 hole through
both sides of 20mm steel box 2mm thick then 5mm dent into my co2 main bottle , ouch !!
