Description

Frostworks Sentinel Stopper #1

Use

Designed to fit into narrow, tapered rock cracks, locking securely when weighted

Context

This Frostworks Sentinel Stopper is part of a full set that has never been used. It is new with tags and was donated by Peggy Denny in 2024. It was in Glen Denny's possession until his death in 2022. These Frostworks nuts were manufactured after Tom Frost created his company Frostworks in 1997. They closely resemble the first MOAC stoppers angles, and were easier to clean than other stoppers.
