Tie Shou heavy-duty rigging shackles are high-strength load-connecting fittings precision drop-forged from quenched and tempered alloy steel (Grade 80 / Grade 100). Manufactured in strict compliance with US Federal Specification RR-C-271 and EN 13889 standards, our anchor bow shackles and chain dee shackles offer Working Load Limits (WLL) ranging from 0.5 Ton up to 85 Tons+ with certified safety design factors of 6:1 and 4:1.

• Bow (Anchor) vs. Dee (Chain) Designs: Bow shackles feature a rounded crown to accommodate multi-leg sling bridles, while Dee shackles excel in heavy in-line straight tensioning.
• Screw Pin vs. Safety Bolt Pins: Screw pin shackles allow quick jobsite connection; Safety Bolt Type (nut & cotter pin) prevents pin backing-out during long-term or high-vibration lifting.
• Drop-Forged Alloy Construction: Exceptional impact toughness and fatigue resistance for extreme offshore, construction, and mining operations.
• Galvanized Finish Protection: Hot-dip galvanized or powder-coated surface provides superior anti-rust durability in harsh marine environments.
