Every shackle is proof-tested before supply.
Our shackles meet or exceed the standard or product specification applicable to the ordered model.
Include required certificates, test records, and traceability details in your RFQ.
Use the groups below to find a suitable pattern, then compare the model drawing and WLL chart.
These endpoints describe each catalogue range; they do not establish the WLL of an intermediate size. Check the marked WLL and drawing for the exact model you order.
| Pattern | Body | Pin | Nominal Size | WLL (Catalogue Units) |
|---|---|---|---|---|
| Grade S Dee — AS 2741 | Dee | Screw pin / safety bolt options* | 6–51 mm | 0.5–35 ton |
| Grade S Bow — AS 2741 | Bow | Screw pin / safety bolt options* | 6–63 mm | 0.5–55 ton |
| G-209 Drop Forged | Bow / Anchor | Screw pin | 3/16–3 in | 1/3–85 ton |
| G-210 Drop Forged | Dee / Chain | Screw pin | 1/4–3 in | 1/2–85 ton |
| G-2130 Drop Forged | Bow / Anchor | Safety bolt | 1/2–4 in | 2–150 ton |
| G-2150 Drop Forged | Dee | Safety bolt | 1/2–4 in | 2–150 ton |
| European-Type Large Bow / Dee | Bow / Dee | Screw pin shown in catalogue | 5–50 mm | 80–8,000 kg |
*The Grade S catalogue shows two pin constructions beside a shared size/WLL table, but no size-by-pin availability list. Confirm the pin type for the requested size before ordering.
For individual dimensions and size conversion, use the full shackle size guide.
| Selection Factor | Bow / Anchor | Dee / Chain |
|---|---|---|
| Shape | Rounded crown | Narrower D-shaped body |
| Connection Space | More room at the crown | Compact inline connection |
| Catalogue Examples | Grade S Bow; G-209; G-2130 | Grade S Dee; G-210; G-2150 |
| Check Before Ordering | WLL, crown fit, bearing area, load direction | WLL, jaw opening, pin fit, load direction |
For more detail on body shape and connection geometry, see the Bow vs Dee shackle comparison.
| Feature | Screw Pin | Safety Bolt |
|---|---|---|
| Pin Assembly | Removable threaded pin | Bolt, nut and cotter pin |
| Forged Catalogue Patterns | G-209 anchor; G-210 Dee | G-2130 bow; G-2150 Dee |
| Selection Check | Assembly/disassembly and pin security for the exact use | Positive pin retention and access for installation and inspection |
Choose the closure for the actual application and the selected model’s instructions. Do not substitute another pin type without confirming the rated configuration.
Send your required WLL, connection dimensions, body and pin type, applicable standard or shackle pattern, material and finish, quantity, and documentation requirements. Powerful Machinery will review your specifications and confirm suitable product options for quotation.
Nominal size is only a starting point. On the drawing for the chosen pattern, check pin diameter, jaw opening, inside width, and length against the mating part. Dimension letters vary between patterns, so use each diagram with its own table.
Include load direction and available clearance with the mating-part dimensions in your RFQ. A pin that fits the hole does not establish a suitable rated connection.
Our how to measure a shackle guide shows where to take each measurement.
The G-209, G-210, G-2130, and G-2150 as drop-forged. Confirm the material and finish for the exact model in your quotation. Galvanizing is a finish; the stainless steel range is a separate material choice.
For corrosive service, compare our separate stainless steel shackle range and specify the exposure and WLL in your RFQ.
All Powerful Machinery shackles are certified, and every shackle is proof tested. Products meet or exceed the standard or product specification applicable to the ordered model. List the certificates, test records, and traceability details you need in your RFQ.
The catalogue lists Grade S bow and Dee shackles under AS 2741 and identifies the U.S.-type G-series by pattern. A pattern name alone does not establish third-party certification. Review any applicable ASME or OSHA use and inspection requirements separately for the job and destination market.
Send the following information for the model and connection you need:
Required WLL and units; intended load direction and application.
Body style (bow or Dee) and pin type (screw pin or safety bolt).
Pin diameter, jaw opening, inside dimensions, available clearance and mating-component dimensions.
Standard or pattern, material, finish and service environment.
Quantity; required markings, certificates, proof-test records and traceability.
Packaging, destination and required delivery date.
For repeat or project orders, attach drawings and any fit tolerances that must remain consistent across shipments.
For bulk, repeat, or OEM orders, send your drawing and requirements for markings, finish, packaging, and documentation. We will review the requested configuration before quotation.
For a program involving multiple components, see our custom OEM rigging hardware capabilities.
Check the shackle’s marked WLL and identification, then inspect the body, pin and pin retention before use. Avoid side loading unless the instructions for that exact model permit it and specify any required WLL reduction. Remove damaged or unidentified shackles from service.
Use the shackle inspection checklist for detailed checks, or the rigging hardware inspection guide for mixed assemblies.
Only if the instructions for the exact model permit it. Follow the specified load direction and any applicable WLL reduction for the selected shackle.
Yes, subject to the model, quantity, and project requirements. Include your marking, private-label, packaging, and documentation specifications with the RFQ for review.
Yes. Specify the service environment, required WLL, material, and finish. We can review suitable forged or stainless steel shackle options for the application.
