Metolius Ultralight Asymmetric Curve Nuts Set #1-10 - Trad Protection

The Metolius Ultralight Asymmetric Curve Nuts Set #1-10 is a full set of ten passive protection nuts that weighs around 30% less than comparable nuts. It's for trad climbers who want a lighter rack and more secure placements in the awkward cracks where standard nuts struggle.

The asymmetric taper is the clever part. Flaring cracks and pin scars are where standard nuts struggle, and the offset shape sits far more securely in them. The straight-sided taper makes it easy to judge placement quality at a glance, and stiffer cables mean the nuts are easier to place in tight cracks and easier to clean afterwards. The collars are colour-coded to match cam colour schemes, so you grab the right size first time. Choose the full set when you're building a trad rack or replacing a worn set of wires in one go.
