Baby got back.

The 12mm Boa HMS 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 carabiner through attachment eyes, and the basket curves nicely to allow central hanging of loaded components.

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.

Locking gate types

Screwgate

Manual locking gate requiring screwing/unscrewing of the barrel to lock/unlock.

Kwiklock

Auto-locking gate requiring two distinct actions to open.

Locksafe

Auto-locking gate requiring three distinct actions to open.

Durolock

Auto-locking gate requiring four distinct operations to open. Force must be maintained throughout or the gate returns to safe (locked).

Kwiklock ANSI

Same gate action as Kwiklock but the connector is also required to exceed 16kN in minor axis, side load and gate face tests.

Locksafe ANSI

Same gate action as Locksafe but the connector is also required to exceed 16kN in minor axis, side load and gate face tests.
