Green Pin Turnbuckles for Rigging and Lifting

Green Pin turnbuckles from Van Beest are forged, proof tested, and manufactured for lifting and rigging service. Holloway Houston is an authorized US distributor carrying Green Pin turnbuckles in eye-eye, jaw-jaw, hook-eye, and jaw-eye body configurations, stocked at our Houston, TX warehouse.

A turnbuckle is a threaded tensioning device: two end fittings, eyes, jaws, or hooks, thread into opposite ends of a central body. Rotating the body tightens or loosens the assembly, allowing length adjustment and tension control on the rigging leg or stay wire it connects.

The primary distinction in the turnbuckle market is between lifting-rated hardware and non-lifting hardware. Rigging screws and turnbuckles sold as commodity hardware typically carry no working load limit rating and no proof test documentation. Lifting-rated turnbuckles, like the Green Pin line, are forged, rated to a documented WLL, proof tested at a defined multiple of WLL, and manufactured to ASME B30.26 (Rigging Hardware), which covers the design, marking, inspection, and use of turnbuckles in load-handling service.

Van Beest manufactures Green Pin turnbuckles for the load-handling market. Holloway Houston stocks the Green Pin line for offshore, industrial rigging, and general lifting applications across the Gulf Coast and nationwide.

Types of Green Pin Turnbuckles

Eye-Eye Turnbuckles

Eye-eye turnbuckles have a closed loop (eye) on each end. The eye on both ends accepts a shackle, master link, or hook. This configuration is the most common in general rigging, the closed eyes prevent the turnbuckle from disconnecting unless the connecting hardware is deliberately removed. Specified for stays, shrouds, and rigging legs where both connection points use shackled fittings.

Jaw-Jaw Turnbuckles

Jaw-jaw turnbuckles have a clevis (jaw and pin) on each end. The jaw and pin connection is faster to install and remove than a shackled eye, the pin drops in without threading. Specified in applications where the rigging leg connects to chain links, flat plate ears, or other hardware that accepts a jaw connection directly. The jaw configuration allows easy rigging and de-rigging in frequent-change applications.

Hook-Eye Turnbuckles

Hook-eye turnbuckles have a hook on one end and an eye on the other. The hook end accepts a chain link, master link, or eye fitting, faster to attach and release than a shackled connection. The eye end provides a permanent shackled connection point. The mixed configuration suits applications where one end of the rigging leg is permanent and the other is frequently changed.

Jaw-Eye Turnbuckles

Jaw-eye turnbuckles combine a jaw fitting on one end with a closed eye on the other. The jaw end attaches to a chain link or plate ear; the eye end takes a shackle or hook. A practical combination when the two connection points involve different hardware types.

Green Pin Turnbuckle Applications by Industry

• Construction Rigging : Rigging leg length adjustment on spreader bar assemblies, stay wire tensioning on temporary structures, and guy wire adjustment during erection work.
• Offshore and Marine : Stay rigging and tensioning on offshore platforms, vessel deck rigging, and mooring system components where lifting-rated hardware is required.
• Oil and Gas : Turnbuckle applications in petrochemical plant maintenance, equipment rigging, and structural tie-off where documented WLL ratings are part of the project specification.
• Shipbuilding : Rigging tensioning and stay wire applications during vessel outfitting where certified hardware documentation is part of the build package.
• Industrial Rigging : General rigging leg tensioning and adjustment in manufacturing, fabrication, and heavy equipment positioning applications.

Why Holloway Houston for Green Pin Turnbuckles

Holloway Houston has been in the rigging hardware business for over 65 years. As an authorized Van Beest Green Pin distributor, we stock lifting-rated turnbuckles, not commodity hardware, in multiple body configurations at our Houston warehouse.

The distinction matters in the field. A Green Pin lifting-rated turnbuckle comes with a documented WLL, a proof test at a defined load, and manufacturer identification marking per ASME B30.26. That documentation package is what a lift plan or offshore project specification calls for. Hardware without it is not a substitute.

Our rigging specialists can confirm the right turnbuckle configuration for the connection points in your assembly, verify the WLL against your load requirements, and pull the proof test documentation at the time of order.

Holloway Houston also provides rigging inspection services, qualified inspectors evaluate hardware including turnbuckles per ASME B30.26 as part of periodic rigging equipment inspections.

Green Pin Turnbuckle Safety and Awareness

Turnbuckles used in load-handling service fall under ASME B30.26 (Rigging Hardware). The following awareness points apply:

• Lifting-rated turnbuckles are marked with the working load limit and manufacturer identification per ASME B30.26. Turnbuckles without legible WLL markings are not suitable for rated rigging service.
• Turnbuckle thread engagement directly affects rated capacity. The body needs to be at or near full take-up for the WLL to apply, a partially threaded turnbuckle has reduced capacity at the end fitting threads. Manufacturer documentation specifies the minimum thread engagement requirement.
• Locking the turnbuckle after adjustment prevents the body from rotating out of position under load. Locking methods include lock nuts, wire through the body, or keeper pins, the appropriate method depends on the turnbuckle configuration and the manufacturer's recommendation.
• Turnbuckles are rated for in-line axial loads. Side-loading a turnbuckle body or end fitting bends the thread area and reduces capacity.
• Visual inspection before each use includes checking for bent bodies, damaged threads, cracked end fittings, and deformation that indicates overload. Hardware showing these signs is removed from service per ASME B30.26.
• Turnbuckles are not repaired by welding or reshaping in the field. Modifications void the manufacturer rating.
