Before You Decide
Confirm the exact Astro Nut 1 size you want before choosing an offer. If the nut will be used for climbing, follow the manufacturer’s instructions and your normal equipment checks before use.

Compare the exact model’s dimensions and rated specifications with the placements you expect to protect, and use climbing protection only in accordance with the manufacturer’s instructions and appropriate climbing training.
