DMM Phantom Screwgate

While it is compact, it is fully functional for belaying. However, because of its smaller size, it may feel a bit tight if you are using thicker ropes or prefer a larger workspace for your belay device.

Yes, the keylock nose design eliminates the notch found on traditional carabiners. This makes it significantly easier to clip and unclip from bolts, slings, and gear loops without getting hung up.

The I-beam construction allows DMM to remove excess material from non-load-bearing areas without compromising strength. This is what keeps the carabiner incredibly light at just 42 grams while maintaining a high 24 kN major axis strength.

Absolutely. Its lightweight design is ideal for alpine routes where every gram counts. The screwgate mechanism is generally reliable in cold conditions, though you should always ensure it is clear of ice and debris before use.

The offset D-shape is designed to shift the load toward the spine, which is the strongest part of the carabiner. This shape also creates a larger gate opening relative to its size, making it easier to clip ropes and gear.
