D-Shaped carabiners encourage loading in their strongest orientation by forcing loads toward the carabiner spine. An Offset D refines this basic design by extending the top bar, increasing internal volume. This improves handling and compatibility with thick ropes and slings.

This carabiner's nose slots into a groove in the gate, allowing it to achieve full strength without a gate notch. This creates a clean internal profile that won't catch on gear, bolts or slings, giving easier clipping and removal from systems.

I-Beam construction techniques allow carabiners to be lighter without compromising strength. This is achieved through hot forging, a process which allows metal to be made into complex shapes that improve functionality.
