Key takeaways
- A wiregate carabiner uses a loop of wire as its gate instead of a solid bar.
- It's lighter and resists 'gate flutter' (momentary opening in a hard fall).
- It's less likely to freeze shut in icy or wet, cold conditions.
- It's very common on quickdraws, slings, and racks where weight matters.

What a wiregate carabiner is
A wiregate carabiner is a non-locking carabiner whose gate is a single loop of stainless steel wire rather than a solid metal bar. The wire loop springs to open and close, and the design has become very popular for its weight and other advantages.
The advantages
- Lighter — the wire gate has less mass, which adds up across a rack.
- Resists gate flutter — in a hard fall the low-mass gate is less likely to bounce open momentarily (which briefly weakens a carabiner).
- Less likely to freeze shut — no spring-loaded hinge cavity to ice up, favored for ice and alpine climbing.
Racking up for an alpine route, a climber chooses wiregate carabiners throughout — shaving grams across dozens of draws and slings, and trusting the gates won’t freeze shut in the cold or flutter open on a hard fall.
When they’re used
Very widely — on quickdraws, alpine draws, and racks generally, especially where weight matters (alpine, ice, trad). They’re typically non-locking; for security-critical connections you still use a locking carabiner such as a screwgate.
The bottom line
A wiregate carabiner uses a wire-loop gate instead of a solid bar, making it lighter, resistant to gate flutter (momentary opening in a hard fall), and less likely to freeze shut. Those advantages make it the dominant non-locking carabiner on quickdraws, alpine draws, and racks — especially for weight-conscious alpine, ice, and trad climbing.
Frequently asked questions
What is a wiregate carabiner?
A wiregate carabiner is a non-locking carabiner whose gate is made from a single loop of stainless steel wire, rather than the solid metal bar of a traditional 'solid-gate' carabiner. The wire loop springs to open and close the gate, and the design has become very popular for its light weight and other advantages.
What are the advantages of a wiregate?
Three main ones: it's lighter (the wire gate has less mass than a solid gate, which adds up across a rack); it resists 'gate flutter' — in a hard fall the low-mass wire gate is less likely to bounce open momentarily, a phenomenon that briefly weakens the carabiner; and it's less prone to freezing shut, since there's no spring-loaded hinge cavity to ice up, making it favored for ice and alpine climbing.
When are wiregate carabiners used?
Very widely — as the carabiners on quickdraws, slings (alpine draws), and on the rack generally, especially where saving weight matters, like alpine, ice, and trad climbing. They're typically non-locking carabiners; for security-critical connections you still use a locking carabiner. Many climbers' racks are dominated by wiregates for their weight and reliability.
