Athletes pushing grade limits, guides managing client groups, and professionals conducting rope rescue training all benefit from the redundant security this carabiner provides. The D-shape keeps loads centered over the spine for maximum strength, while the modified design sits comfortably in your palm and clips securely into bolts without rotating unexpectedly.
