The full-sized, but very light, wire gate biners won't catch on bolts or slings, making them excellent for desperate clips on hard redpoints.
- Nitro biners replace the Helium. I-beam, ribbed construction is strong and lightweight.
- Biner shape and narrow neck (best used with thin-gauge slings) keep the sling close to the spine.
- Notch-free noses won't catch, hooded to prevent them from opening when rubbing against the rock.
- Wire gates are flat against the clipping surface, not turned. This resists gate flutter, and slightly increases the gate opening.
