Stainless Steel Screw Pin Semi-Round D Shackle Long Type

The elongated "D" profile allows for increased internal length (L), improving clearance and flexibility when connecting hardware in constrained or recessed setups. The screw pin closure ensures secure load retention and easy removal or repositioning.

Key Specifications:

• Material: SUS304 stainless steel

• Thread Type: Fine pitch, metric (M5, M6, M8 depending on size)

• Available Sizes: D = 5 mm, 6 mm, 8 mm

• Working Load Limit (WLL): Up to 200 kgf (1.96 kN)

• Finish: Highly polished for smooth handling and corrosion resistance

Applications:

• Precision lifting or tie-down in tight vertical clearances

• Marine rigging where corrosion resistance is critical

• OEM and industrial hardware assemblies requiring compact but strong shackles

Use Cases for Long-Type Semi-Round D Shackles

1. Marine and Offshore Rigging
   The SUS304 construction offers excellent corrosion resistance against saltwater, making these shackles ideal for:

   • Securing ropes, chains, or wire rope on sailboats, yachts, and docks

   • Connecting anchor lines or mooring components where a longer reach is required

2. Architectural and Structural Applications
   In stainless tension rod systems, suspension cables, or decorative installations, the long profile allows:

   • Clean alignment between spaced anchor points

   • Integration into modern architectural hardware where aesthetic polish and functionality are both needed

3. Industrial Equipment and Machinery
   These shackles serve as compact connectors in mechanical or load-bearing assemblies:

   • Attaching lifting slings or hoists where deeper throat clearance (L) improves accessibility

   • Linking parts in confined assemblies without sacrificing tensile strength

4. Theatrical Rigging and Truss Systems
   In stagecraft and lighting setups, the long-style shackle provides:

   • Easy rigging around structural beams or pipes

   • Secure, adjustable links for overhead equipment where visibility and safety are key

5. Renewable Energy Installations
   In wind or solar farm structures exposed to the elements, these shackles:

   • Withstand harsh environmental cycles

   • Serve as non-permanent connections in cable routing or maintenance support hardware
