Bolt Type Chain Shackles (Dee Shackles)

Bolt Type Chain Shackles (Dee Shackles)

Holloway Houston stocks the premium Green Pin® G-4153 series. Manufactured in The Netherlands, these are the gold standard for heavy-duty rigging. Featuring a Bolt Type safety pin with a nut and cotter pin, they are engineered for permanent or long-term installations where vibration might otherwise loosen a standard screw pin.

The Green Pin Advantage

• Superior Metallurgy : The bow and pin are forged from high-tensile Grade 6 alloy steel, Quenched and Tempered. This ensures ductility if overloaded, the shackle will deform visually before failing, providing a critical safety warning.
• Bolt Type Security : The safety bolt, nut, and stainless steel cotter pin mechanism ensures the shackle remains secure even under dynamic rotation or vibration. This is mandatory for many offshore and subsea applications.
• Galvanized Durability : Hot Dipped Galvanization provides long-term corrosion resistance in marine environments.

Dee Shackle vs. Bow Shackle

It is critical to choose the right shape for your lift.

• Use a Dee Shackle (This Category): For "One-to-One" connections. Perfect for joining two chains, connecting a sling to a beam clamp, or lifting spreader beams where the load is applied in a straight line.
• Use a Bow Shackle : If you need to attach multiple sling legs to a single shackle or if the load will be applied at an angle (side-loading).
