The shape of the carabiner frame has an influence on:

• major axis strength

• load distribution

• gate opening size, and capacity

• strength in certain positions

• ease of handling

Another less obvious effect is the balance of the carabiner itself: for example pear-shaped carabiners rotate more readily, which can result in poor positioning. D-shaped carabiners tend to stay in place better.
