The Petzl Bm’D asymmetrical carabiner is a lightweight, high-strength connector designed for efficient integration with work-at-height equipment. Its D-shaped geometry is particularly suited for connection to descenders and positioning lanyards. Constructed from aluminum, it helps reduce carried weight while maintaining durability. The fluid interior design and Keylock system improve handling, while the TRIACT-LOCK automatic locking mechanism provides secure, triple-action gate operation.
