The DMM Steel Boa HMS Karabiner has all the 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 high internal volume are required. The smooth rounded internal form is very useful when rotating the karabiner through attachment eyes, and the basket curves nicely to allow central hanging of loaded components.

The high working load, large size and durability make this karabiner ideal for rigging where heavy loads are involved
