The line is listed as compatible with a range of Grainger part numbers including 13R481, 13R482, 13R484, 1VN79, 1VN80, 29JU84, 29JU85, 33W158, and the 492P series from 492P72 through 492P82 plus 6DLV3. Verify your winch model against this list before ordering.

Questions about this item

Does the package include any hooks, thimbles or mounting hardware, or must they be purchased separately?

The listing describes only the synthetic winch line itself — 5/16 in diameter, 50 ft long, grey, rated at 4,400 lb. No hooks, thimbles or mounting hardware are mentioned, so assume they are not included.

The title shows a single diameter and length — 5/16 in by 50 ft. Are there other versions of this Lockjaw line to choose from?

The supplier data lists only this 5/16 in, 50 ft grey line under part number 20-0313050. No alternative diameters, lengths or colours are referenced for this product.

What does the 4,400 lb maximum load capacity mean when the line is on a winch drum under real load?

The 4,400 lb figure is the rated breaking strength of the synthetic rope. Actual safe working load depends on the winch, the application and any safety factors you apply; the line is also noted as compatible with Grainger part numbers 13R481, 13R482, 13R484, 1VN79, 1VN80, 29JU84, 29JU85, 33W158 and the 492P72–492P82, 6DLV3 series.
