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 P-6953 Snatch Block T is a tail-board style snatch block designed for bolted or welded attachment to structures. The tail plate provides a fixed mounting point, making this block ideal for permanent or semi-permanent wire rope directional change installations.
Key Features
- Tail-board mounting plate for bolted or welded installation
- Side-opening cheek plate for wire rope access
- Heavy-duty sheave reduces friction and rope wear
- Forged steel frame
- Individually proof tested with certificate
Common Applications
- Permanent wire rope directional change points
- Fixed winch and hoist installations
- Structural mounting on equipment and platforms
- Marine and industrial fixed-mount applications
Why Green Pin?
The P-6953 tail-board design creates a permanent, certified directional change point. Individually proof tested by Van Beest for consistent quality in fixed installations.
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).
