The DMM 12mm Boa HMS features a tough and rugged construction. It is cold forged and heat treated to offer the highest levels of strength, it also features a zinc coating to provide protection against corrosion. The large 24mm gate opening makes it ideal for rigging applications where you may need to accommodate ropes with knots.
HMS for space and rigging: HMS connectors are pear shaped and often have similar characteristics to ovals in how they deal with loaded components, i.e. they also allow devices and connectors to self-centre. Moreover, the extended basket allows for additional component connection. Knots in a system such as an Italian hitch can rotate easily between taking in and paying out (even with larger diameter ropes). In general, HMS connectors are slightly oversized to accommodate the added volume of bigger ropes and to feel secure in a gloved hand.
