Traditional D-shaped aluminum carabiner is part of the basic food groups for a climbing rack. The perfect item to bulk up on, as you can never have enough of them.

• D shape distributes loads along the spine of the biner for increased strength and safety
• Doesn't work well with pulleys, belay devices, or ascenders; use a locking jake or oval locking biner for those applications
• 15 mm gate opening
• CE certified
