Specifications — Full Dimensions by Size
This is below the 5:1 commonly specified for wire rope and synthetic sling systems (4:1 is standard for alloy chain components under ASME B30.9). Where a 5:1 column is shown it is SlingCenter’s derate — the manufacturer’s figure remains the rating of record.

The 4:1 column is the manufacturer’s published Working Load Limit and is the rating of record — the figure marked on the product. The 5:1 column is calculated by SlingCenter as WLL × 4 ÷ 5, for comparison against components rated at the 5:1 commonly specified for wire rope and synthetic sling systems. It is always the lower of the two. We never restate a Working Load Limit upward. Pound figures are converted by SlingCenter from the manufacturer’s metric rating at 1 t = 2,204.62 lb and rounded down — a unit conversion only, not a change of rating. The metric figure is the rating of record. Lowercase t is the metric tonne (1,000 kg / 2,204.62 lb), the manufacturer’s own notation — not the US short ton.
The Green Pin MJS Round Web Sling Connecting Link is a mechanical connecting link specifically designed for roundsling connections. The link geometry accommodates the round cross-section of roundslings, providing a secure connection point without the bunching and chafing that standard links cause on round slings.
Key Features
- Geometry optimized for roundsling connections
- Mechanical (bolted) assembly
- Reduces sling chafing and bunching
- Individually proof tested with certificate
- Compatible with standard roundsling diameters
Common Applications
- Roundsling-to-chain connections
- Roundsling assemblies requiring intermediate links
- Sling system modifications in the field
- Mixed-media sling systems
Why Green Pin?
The MJS is purpose-built for roundslings — no more forcing round slings through hardware designed for flat slings. Van Beest's individual proof testing ensures reliable capacity at every connection.
Safety & Standards
Every product we carry is individually marked with Working Load Limit (WLL), manufacturer traceability code, and country of origin. Inspection and mill certificates are available on request — email sales@slingcenter.com with your order number.
Governing Standards
- ASME B30.9 — slings (web, round, wire rope, chain) inspection and use
- ASME B30.26 — rigging hardware (shackles, eye bolts, links, turnbuckles)
- ASME B30.10 — hooks
- OSHA 1910.184 and 1926.251 — general industry and construction sling safety
- WSTDA WS-2 and RS-1 — web and round sling design
- 49 CFR 393.102 to 393.130 — DOT cargo tie-down
- NACM — welded steel chain grade specs
Inspection & Safety
Before every use: visual check for cracks, corrosion, distortion, wear, and illegible markings. Annually (minimum): documented periodic inspection by a trained inspector. Remove from service at first sign of damage. Never repair rigging hardware by welding, heating, or bending.
WARNING: Improper use of rigging can cause death or serious injury. Never exceed the rated Working Load Limit. Apply derating for side-loading, elevated temperature, or chemical exposure. Final application decisions must be made by a Qualified Person per OSHA 1926.32(m).
