| Gate | Loop of stainless wire |
| Pros | Light, freeze-resistant, no flutter |
| Common on | Quickdraws, alpine racks |
| Difficulty | Beginner |
A wiregate carabiner uses a loop of stainless wire as its gate instead of a solid bar. This makes it lighter, less prone to freezing or icing shut, and resistant to ‘gate flutter’ — the gate momentarily vibrating open during a fall. Wiregates are popular on quickdraws, slings, and alpine racks.
Why climbers use them
Lighter for big racks, reliable in the cold, and flutter-resistant — ideal for alpine and trad kits and quickdraw rope ends.
Still fully strong
Wiregates meet the same standards as any carabiner; for locking versions see the screwgate.
Frequently asked questions
What's the difference between a wiregate and a solid gate carabiner?
A wiregate's gate is a loop of wire rather than a solid bar, making it lighter and giving its gate less mass. Solid gates feel sturdier and often clip very smoothly, while wiregates resist icing and gate flutter — many climbers use solid gates on the bolt end of a quickdraw and wiregates on the rope end.
Are wiregate carabiners as strong?
Yes — wiregates meet the same strength standards as solid-gate carabiners and are fully climbing-rated. Their lighter gate is actually an advantage in a fall, since it's less likely to flutter open momentarily.
Why use wiregate carabiners?
For weight savings on big racks, reliable function in cold and icy conditions where solid gates can freeze, and reduced gate flutter. This makes them especially popular for alpine and trad climbing and on quickdraw rope ends.
