DMM Big Boa HMS 30 kN Locksafe triact lock climbing carabiner

The DMM Big Boa HMS 30 kN Locksafe triact lock climbing carabiner is designed for rescue operations, recovery maneuvers, climbing, and working at height.Here’s what DMM says about the Big Boa HMS 30 kN Locksafe.The Boa is a high-volume carabiner with a wide gate opening and an extended top bar, making it easy to clip with thick ropes and slings, allowing for more attachments. Its asymmetric shape naturally fits the hand for easy handling, and the I-Beam construction means that despite its generous size, the Boa is still relatively lightweight.Anchor carabiners are used at critical connection points in anchoring and rigging systems. They are designed to be robust, with wide gate openings, extended internal volumes, and baskets for ropes. This makes them easier to handle with gloves and allows them to accommodate thick ropes, multiple knots, or slings.HMS carabiners have extended top bars to accommodate more attachments like slings and knots. Their top bars are curved, allowing attachments to center automatically and promote optimal loading. HMS carabiners tend to be large for better compatibility with thick ropes and the use of gloves.The gate opening is the distance between the nose of a carabiner and the gate when it is fully open. Wider gate openings make the carabiner easier to use with gloves and with thick ropes and slings. The internal volume refers to the area inside a carabiner, and large internal volumes mean easier attachment and removal of multiple devices, knots, and slings.The nose design of these carabiners helps them resist shear forces and achieve high ratings for side load strength. The Taperlock is an evolution of our Keylock design, offering a clean internal profile that prevents snagging on gear, bolts, and slings.I-Beam construction techniques allow carabiners to be lighter without compromising strength. This is achieved through hot forging, a process that allows the metal to take on complex shapes that enhance functionality.
