30kN Boa HMS

The Big Boa is a large volume rigging carabiner perfect for using as the central connection point in an anchor system. It shares the ergonomics and high volume of the standard Boa carabiner, but is made from 14mm bar rather than 12mm bar for increased strength. A 30kN major axis means this version of the Big Boa can be used for rescue loads, whilst the 12kN minor axis strength gives extra safety margins if accidentally cross loaded.

The carabiner comes as standard with a matt grey anodised finish, but can also be supplied with a matt black anodised finish or with more specialist Ceracote finishes in a range of tactical colours from artic white to desert coyote. The Ceracote coatings are also available with a reduced IR signature.

Rigging carabiner for strength and ease of handling

Rigging carabiners are used at critical connection points in rigging and anchor systems. They are built to be strong, and have large gate openings, internal volumes, and extended rope baskets. This makes them easier to handle with gloves on, and allows them to accommodate thick ropes, and multiple knots or slings.

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.

Taperlock nose gives high push-in strength

The nose design on these carabiners helps them resist shearing forces and achieve high side loading strength ratings. Taperlock is an evolution of our Keylock design, which gives a clean internal profile that prevents snagging on gear, bolts and slings.

I-Beam construction for optimum strength to weight ratio

I-Beam construction techniques allow carabiners to be lighter without compromising strength. This is achieved through hot forging, a process which allows metal to be made into complex shapes that improve functionality.

Boa product features

An overview of the features and benefits of the Boa carabiner.

Durolock connector locking mechanism

Our unique Durolock mechanism minimises the chance of accidental gate opening. Earlier this year the versatile Ultra O connector was our fourth locking carabiner to be paired with this option. Watch this short video to find out more about the Durolock.
