Ronstan Standard Dee Slotted Pin Shackle - 3/16" Pin - 23/32"L x 13/32"W

The Ronstan Standard Dee Slotted Pin Shackle with 3/16" Pin is a marine-grade rigging fastener designed for sailors, riggers, and equipment managers who demand reliability in demanding environments. This compact shackle (23/32"L x 13/32"W) serves as a critical connection point in sailing systems, cargo securing, and tactical equipment rigging where secure yet accessible fastening is essential. Built to withstand saltwater exposure and repeated use, it has become a standard choice for both professional maritime operations and serious recreational boaters.

The key advantage of this shackle lies in its slotted pin design, which is engineered as a low-profile fastener to prevent snagging on ropes, lines, or canvas during operation. Constructed entirely from Grade 316 stainless steel—both the body and pin—this shackle offers superior corrosion resistance compared to standard 304 stainless or galvanized alternatives, making it ideal for saltwater and chemically aggressive environments. The slotted pin mechanism allows quick manual removal without requiring separate cotter pins or tools, streamlining rigging adjustments and emergency disconnects while maintaining secure, vibration-resistant locking under load.

This shackle is best suited for boatowners, sailing teams, and tactical equipment specialists working with deck hardware, running rigging, or cargo systems where quick-release functionality meets uncompromising durability. Its compact footprint and low-snag profile make it particularly valuable in confined spaces or high-friction environments where standard shackles create catch points. Compatible with standard 3/16" rigging pins and compatible with most dee-ring attachment points, the Ronstan RF150 integrates seamlessly into existing marine hardware systems and will deliver years of reliable service with minimal maintenance beyond periodic freshwater rinses.
