Ronstan Standard Dee Shackle - 9.5mm (3/8") Pin

The Ronstan Standard Dee Shackle with 9.5mm (3/8") pin is a marine-grade hardware component engineered for rigging, sailing, and tactical equipment applications where secure, reliable connections are non-negotiable. Designed for professionals and enthusiasts who demand precision fastening in high-stress environments, this dee shackle serves as a critical load-bearing link in rope systems, harnesses, and field gear configurations. Its compact yet robust design makes it suitable for both permanent installations and field-deployable setups where weight and strength must be carefully balanced.

Manufactured from Grade 316 stainless steel, both the shackle body and pin deliver exceptional corrosion resistance and durability in saltwater, chemical, and extreme-weather conditions. The coined shackle pin head features a specialized hole for seizing wire, allowing users to permanently lock the pin in place and prevent accidental release under dynamic loads or vibration. This design detail is critical for safety-critical applications where pin retention cannot be left to chance. The high strength-to-weight ratio—achieved through advanced material selection and precision engineering—ensures that users gain maximum load capacity without unnecessary bulk, making it ideal for weight-conscious tactical and maritime operations.

Users in military, search-and-rescue, sailing, and industrial rigging environments benefit most from this shackle's reliability and field-proven construction. The 9.5mm pin diameter accommodates standard rope sizes and sling configurations used across professional and civilian sectors. Installation is straightforward: simply align the shackle with your anchor point or hardware loop, insert the pin, and secure it using seizing wire threaded through the dedicated hole. With dimensions of 2 x 1 x 3 inches and a weight of just 0.2 lbs, this shackle integrates seamlessly into modular gear systems without compromising mobility or load distribution. Its stainless steel composition ensures long service life even in corrosive environments where standard steel would deteriorate rapidly.
