Lighter, Smarter Passive Protection

The Metolius Ultralight Asymmetric Curve Nuts are designed for climbers who want maximum placement security with minimal weight.

Featuring an asymmetric curved taper, these nuts sit more securely in flaring placements and pin scars-giving you more confidence when it matters most. The straight-sided taper also makes it easier to visually assess placement quality at a glance.

Built to be 30% lighter than comparable nuts, they're ideal for climbers looking to reduce rack weight without sacrificing performance.
