The 12mm Boa HMS in steel has all the strengths and versatility of its alloy sibling, but has a rated strength of 40kN! It can be used for many applications where a large gate opening or large internal volume are required.

The smooth rounded internal form is very useful when rotating the carabiner through attachment eyes and the basket curves nicely to allow central hanging of loaded components (minimising the scary clicking associated with extreme D shaped connectors).
