DMM Boa HMS Carabiner

The DMM Boa HMS Carabiner is a high-strength, large-format connector designed for demanding arborist, rigging and rescue applications. Hot forged from 14mm aluminium bar, the Boa delivers an impressive 30kN major axis strength, making it ideal for heavy-duty use where reliability is critical.

Featuring a generous HMS (pear-shaped) basket, the Boa is built to handle complex systems with ease. Whether you're running multiple ropes, attaching rigging devices or setting up rescue systems, the large curved basket allows equipment to sit comfortably and operate smoothly without crowding.

The oversized design also makes the Boa exceptionally easy to handle, even when wearing thick gloves. Its ergonomic shape and wide gate opening ensure efficient clipping and operation in demanding working conditions.

Equipped with DMM’s patented Taperlock nose, the Boa provides increased gate strength while maintaining a clean, snag-free connection for ropes, slings and hardware.
