C. Sherman Johnson 15-212 Quick-Release Shroud Adjuster 7-Hole 1/4" Pin

The C. Sherman Johnson 15-212 Quick-Release Shroud Adjuster is purpose-built for dry-sailed, one-design dinghies, delivering fast, tool-free rigging tension adjustments right on the water or on the dock. With 7 adjustment positions, sailors can dial in precise rig tension for varying wind conditions, while the lever mechanism provides a pin-to-pin adjustment range of 1-3/4" to 3-5/8". When rig tension has been set, an included quick-release locking pin secures the lever firmly in place for racing or pleasure sailing.

Pulling the quick-release pin instantly frees the lever for effortless re-tensioning or full de-tensioning — ideal for unstepping the mast or stowing the rig after a sail. Built from 316 stainless steel throughout, this shroud adjuster delivers long-lasting strength and excellent corrosion resistance in demanding marine environments.
