12mm Boa HMS

The 12mm Boa HMS 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 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.

Kwiklock
Kwiklock - Auto-locking gate requiring two separate actions to open. Kwiklock gates are suitable when auto-locking gates are a necessity, but rigging systems are relatively static and anchor points are easy to monitor.
ANSI Kwiklock
ANSI Kwiklock - A very strong auto-locking gate requiring two separate actions to open. Kwiklock gates are suitable when auto-locking gates are a necessity, but rigging systems are relatively static and anchor points are easy to monitor. ANSI
Kwiklock gates rate to a minimum 16kN in minor axis, side loading and gate face loading tests, and conform to ANSI Z359.12 (2009).
Locksafe
Locksafe - An auto-locking gate requiring three separate actions to open. Locksafe gates give extra security in complex rigging systems such as those featuring running ropes or remote anchor points.

Screwgate
Screwgate - Non auto-locking gate which requires two actions to open, and is easy to use with one hand. Screwgates are suitable in systems where anchor points can be easily monitored and are unlikely to be affected by running ropes.
