DMM Ultra D (Titanium/Lime)

The Ultra D is a very strong and versatile high-volume carabiner that is suited to heavy duty rigging and rescue work. The carabiner's shape is a hybrid of the Ultra O and the Zodiac shapes; the resulting longer top bar, wider gate opening, and larger internal volume makes it very easy to use with gloves and when working with thick rope and slings. Plus, the ability for it to accommodate knots at either end and hold pulleys symmetrically makes it very versatile in rigging systems.
