Green Pin Screw Bow Shackle

Product Description

Green Pin Screw Bow Shackle

Green Pin Screw Bow Shackles are high-quality, heavy-duty shackles designed for secure connections in marine, offshore, lifting, towing, mooring and industrial rigging applications. Manufactured from Grade 6 high-tensile steel that is quenched and tempered, these Green Pin bow shackles are built for demanding working environments where strength, safety and dependable performance are essential.

The bow-shaped design provides additional clearance compared with a Dee shackle, allowing the shackle to accommodate chains, ropes, wire rope, slings and other compatible rigging components. This makes the Green Pin Screw Bow Shackle a versatile choice for marine mooring systems, lifting arrangements, towing equipment, port operations, boatyard work and offshore applications.

The screw collar pin allows quick assembly and removal, making this type of shackle especially useful for rigging activities where connections need to be installed, adjusted or dismantled regularly. The screw thread is protected within a chamber in the shackle eye, helping to reduce wear on wire rope and connected equipment.

Marine and mooring applications

Green Pin Screw Bow Shackles are suitable for a range of marine and mooring applications, including connecting anchor chains, attaching mooring equipment, securing buoys and sinkers, joining chain assemblies and connecting ropes or cables to fixed points. They are suitable for use by marinas, boatyards, ports, harbour authorities, marine engineers, commercial vessel operators and offshore contractors.

They can also be used when assembling or maintaining temporary and adjustable mooring systems, provided the correct shackle size, working load limit and connection method have been selected. The galvanised finish provides protection for outdoor and marine equipment, although regular inspection remains essential in saltwater and demanding operating conditions.

Lifting, towing and rigging applications

The Green Pin Screw Bow Shackle is suitable for both one-leg and multi-leg lifting systems. Typical applications include connecting chain slings, wire rope slings, lifting accessories and compatible lifting points. The bow profile provides useful flexibility where connections involve several components or where the load direction may vary within the limits of the approved lifting arrangement.

These shackles are also suitable for towing and recovery equipment, heavy-duty load securing, construction site rigging, offshore maintenance, port handling and industrial lifting work. Their quick-release screw collar pin makes them practical where equipment is regularly connected and removed.

Always select the correct Green Pin Screw Bow Shackle according to the required working load limit, chain or rope size, connection dimensions and intended application. Shackles used for lifting must be inspected and used in accordance with the relevant lifting and safety requirements. Screw pin shackles are generally intended for temporary or regularly adjusted connections and should not be used where the pin may rotate or loosen without suitable safety measures.
