DMM Big Boa HMS Screwgate Karabiner – 3 Pack



DMM Boa Alloy Karabiner Screwgate – Pack of 3. If you are looking for a reliable, high volume carabiner that is versatile, sturdy, and ergonomic, the DMM Boa Alloy Karabiner Screwgate is the perfect match for you. Featuring a large gate opening plus an extended top bar, the Boa makes it really easy to clip with thick slings and thick ropes, also allowing it to accommodate multiple attachments. Its screwgate mechanism is a non auto-locking gate requiring two actions for it to open, and is easy to handle with one hand. This system is best in systems where your anchor points can be easily monitored and are not likely to be disturbed by running ropes.

The DMM Boa’s asymmetric shape sits comfortably and naturally in your hand for easy handling. Despite its large size, the Boa is still relatively light due to its I-Beam construction.
