HMS STEEL Ref:K0009
This is the same style as the alloy the same in its uses, but this is the one I would recommend as the all rounder steel karabiner. For industrial rescue and rope access it is ideal.

The karabiner is made from high grade steel, formed from round bar, has a screw gate and its strength has been increased to 40kN making it the ideal Karabiner for industrial use in technical access and rescue as team kit
Material: Steel, Zink plated, yellow passivation.
