Big Boa Duralock 30 kN (Spring 2023)



High-volume rigging carabiner with ultra-secure 4-stage gate

The Boa is a high volume carabiner with a large gate opening and extended top bar, making it easy to clip with thick ropes and slings, and allowing it to accommodate multiple attachments. Its asymmetric shape sits naturally in the hand for easy handling, and I-Beam construction means that despite its large size, the Boa is still relatively light.

Durolock - An auto-locking gate requiring four separate actions to open. The most secure gate in complex and dynamic rigging systems, the Durolock maximizes protection from accidental gate opening.

Other Features:
• Ideal for rigging: HMS carabiners have extended top bars to accommodate multiple attachments like slings and knots. Their top bars are curved, allowing attachments to self-center 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
-- 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 DMM's Keylock design, which gives a clean internal profile that prevents snagging on gear, bolts and slings.
-- I-Beam construction allows the Boa 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.
