Sea-Dog Line 147004 D Shackle Cast 316 Stainless Steel 3/16 Inch

The Sea-Dog Line 147004 is a marine-grade D shackle constructed from investment cast 316 stainless steel for superior corrosion resistance in harsh saltwater environments. This heavy-duty rigging component features a distinctive D-style design with straight parallel sides and a rounded U-shaped bottom.

Key Features:

• Investment cast 316 stainless steel construction resists corrosion and maintains strength
• 3/16 inch pin diameter for secure attachment
• D-style design optimized for bidirectional load applications
• Rounded U-shaped end distributes heavy loads effectively
• Threaded screw pin for easy installation and removal
• Ideal for marine rigging, anchoring, and deck hardware connections

Application Notes: The U-shaped end of this shackle is engineered to handle heavy loads efficiently. Loads applied to the straight sides may cause bending and should be avoided. As with all cast shackles, this product is not load-rated and should be used with appropriate safety margins for your specific application.

Perfect for sailboat rigging, powerboat anchoring systems, dock lines, and general marine hardware applications where stainless steel durability is essential.
