Ronstan Trunnion Snap Shackle - Large Swivel Bail - 122mm (4-3/4") Length

The Ronstan Trunnion Snap Shackle with Large Swivel Bail is engineered for securing recovery equipment, tie-down systems, and load-bearing applications where reliability and durability are non-negotiable. Whether you're rigging a winch system on an off-road vehicle, securing cargo during transport, or setting up towing infrastructure, this 122mm (4-3/4") shackle delivers the articulation and strength required in demanding automotive and marine environments. Its trunnion swivel design is purpose-built for situations where loads shift direction or need to absorb movement without binding or limiting attachment angles.

Constructed from Grade 15-5PH investment cast stainless steel body and hasp, this snap shackle combines corrosion resistance with exceptional strength—critical when exposure to salt spray, moisture, or harsh environments is a factor. The Grade 316 stainless steel plunger pin mechanism ensures smooth, reliable engagement while resisting seizing or degradation over time. The trunnion swivel head permits full 360° rotation and side-to-side articulation simultaneously, allowing the shackle to accommodate multi-directional loads without stress concentration or premature failure at the attachment point. This design eliminates the need for separate swivel adapters, reducing weight and complexity in your rigging assembly.

This shackle is ideal for vehicle recovery systems, cargo securement, marine-grade applications, and any setup requiring corrosion-resistant hardware rated for continuous articulation under load. The compact 0.5 lb weight and manageable 122mm length make it suitable for confined spaces while maintaining robust load-carrying capability. Mechanics and fabricators favor Ronstan hardware for off-road build-outs, trailer tie-down systems, and winch rigging where stainless construction prevents rust bloom and ensures longevity in extreme conditions. Verify compatibility with your existing hardware by confirming shackle diameter and load ratings match your application's specifications.
