12mm Boa HMS

The 12mm Boa HMS has a wide gate opening for easy clipping of thick ropes and slings, and large internal volume for controlled handling in all conditions. It's curved top bar allows multiple attachments which can centralise under load for stable loading.

HMS carabiner for ease of rigging

HMS carabiners have extended top bars to accommodate multiple attachments like slings and knots. Their top bars are curved, allowing attachments to self centre and encouraging optimal loading. HMS carabiners tend to be large, for better compatibility with thick ropes and while wearing gloves.

Large gate opening and high internal volume for easy handling and more attachment options

The gate opening is the distance between the nose of a carabiner and the gate when it is fully opened. Larger gate openings make a carabiner easier to use while wearing gloves, and with thick ropes and slings. Internal volume refers to the area inside a carabiner, and large internal volumes mean easier attachment and removal of multiple devices, knots and slings.

12mm bar section for maximum strength

These carabiners use thick 12mm bar to achieve very high strength ratings. They are suitable for heavy duty rigging operations where strength is paramount.

Cold forged and heat treated steel for high strength and durability

Steel carabiners are very strong and hard wearing, making them suitable for scenarios with high loads and heavy use. Cold forging means carabiners retain full section bars for consistent rope handling, while heat treatment results in high tensile strength.

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 - 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 - 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.

ANSI Locksafe - A very strong auto-locking gate requiring three separate actions to open. Locksafe gates give extra security in complex rigging systems such as those featuring running ropes and remote anchors. ANSI Locksafe gates rate to a minimum 16kN in minor axis, side loading and gate face loading tests, and conform to ANSI Z359.12 (2009).

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.
