DMM Boa Carabiner

A large locking carabiner perfect for rigging and use as a central connection point . With drop-forged I-beam construction its pretty light too!

One of the great rigging carabiners of our time - large enough to accommodate at least two large 11mm clove hitches and has a wide (25mm) gate opening.  Due to its drop forged, I-beam construction, DMM have managed to reduce the weight by almost 25% when compared to the original Boa.  As with other DMM carabiners, the shape and function has been well done allowing easy handling even in gloves making it appealing for winter climbing, rock climbing and centre use.
