Stainless Steel Safety Pin Long D Shackle
The Safety Pin Long D Shackle, designated under the SBML series, is a high-strength rigging component designed for demanding marine, lifting, and structural applications. Constructed from corrosion-resistant stainless steel (SUS304 or SUS316), it provides excellent durability in harsh environments—making it ideal for offshore, marine hardware, and industrial rigging systems.
Design & Features:
This shackle features an elongated "D" (or "U") body with increased internal clearance, offering improved versatility for connections involving multiple components or bulky fittings. The defining safety feature is its dual-locking system: a standard hex nut combined with a cotter (split) pin, which secures the shackle pin against accidental loosening due to vibration or dynamic loads.
Key dimensions include:
D (Pin Diameter): Ranges from 14 mm to 25 mm
L (Inner Length): 104 mm to 200 mm
B (Inner Width): 26 mm to 50 mm
Thread Size: M14 to M24
Performance:
The Working Load Limit (WLL) for the SBML series spans from 900 kgf (8.82 kN) in the SBML-13 to 3200 kgf (31.36 kN) in the SBML-25, reflecting a wide spectrum of use cases—from light-duty rigging to heavy industrial loads. Weight per unit increases proportionally with size, peaking at 2.74 kg for the largest shackle.
Applications:
Load securement and lifting operations
Marine rigging and mooring systems
Structural suspension points
High-vibration or critical safety environments where redundancy in fastening is essential
The SBML shackle’s robust mechanical locking system, coupled with premium stainless steel construction, makes it a reliable choice for engineers and field professionals requiring both performance and safety.
