Ronstan Wide Dee Shackle - 3/8" Pin - 2-7/32"L x 1-5/32"W

The Ronstan Wide Dee Shackle with 3/8" Pin is a precision-engineered rigging component designed for marine, industrial, and tactical applications where reliable load attachment is critical. This shackle serves as a versatile connection point in rope systems, slings, and hardware assemblies where secure, corrosion-resistant fastening is non-negotiable. Built to withstand demanding environments—from saltwater deck operations to field deployments—the wide dee shackle distributes load stress more effectively than narrow designs, making it the preferred choice for users who prioritize durability and safety in high-consequence scenarios.

The 3/8" pin diameter provides substantial strength while maintaining a high strength-to-weight ratio—a hallmark of Ronstan's engineering philosophy. The wide dee profile increases the bearing surface area, reducing point-load stress on connected materials and extending service life in friction-prone applications. At 2-7/32" length by 1-5/32" width, this shackle fits seamlessly into compact rigging systems without sacrificing load capacity, making it ideal for situations where space is limited but performance cannot be compromised. The die-cast or forged construction (typical for Ronstan hardware) ensures consistent material properties and minimal tolerance variation across production runs.

Professional users—including boat riggers, rope access technicians, outdoor enthusiasts, and tactical operators—rely on this shackle for anchor points, tether systems, and load-bearing connections where failure is not an option. Its compact footprint and robust pin design make it compatible with standard 3/8" hardware, allowing integration into existing rigging assemblies without modification. Whether used in permanent installations or portable field configurations, the Ronstan Wide Dee Shackle RF640 delivers the reliability and precision expected from a market-leading manufacturer with decades of heritage in critical-use hardware.
