The Zodiac series has been designed to be the ultimate offset D rigging carabiner with massive reserves of strength and great durability. DMM thinks that they've succeeded.
The Zodiac carabiners are hot forged from raw 12mm bar to become the perfect rigging carabiner with great strength and friendly rope surfaces. The carabiner has a massive major axis strength of 32kN, a minor axis strength of 12kN and an open gate strength of 12kN. Very few other carabiners achieve this.
