Grade 80 Alloy Chain for Overhead Lifting
This Dayton 5WRR7 chain is built for lifting applications that require Grade 80 alloy steel. It suits riggers, maintenance crews and industrial buyers who need a 1/2 in trade size with a 12,000 lb working load limit. The 20 ft length and straight link design provide a ready-to-use length for sling assemblies or direct attachment. It is not for buyers who need a shorter cut length or a chain with pre-fitted hooks.
12,000 lb Working Load Limit Across 20 ft
The chain delivers a working load limit of 12,000 lb over its full 20 ft length with eight links per foot. Each straight link measures 1 5/8 in inside length and 3/4 in inside width, giving consistent engagement with compatible Grade 80 fittings. Headroom ends at the rated limit; loads beyond 12,000 lb exceed the design capacity. No hook is included, so the usable length depends on the end fittings selected by the installer.
Black Oxide Finish Withstands -40 to 400 Degrees F
A black oxide coating protects the alloy steel across a minimum operating temperature of -40 Degrees F and a maximum of 400 Degrees F. The finish resists corrosion during normal lifting cycles without adding measurable friction. No lubrication schedule or cooling requirement is specified by the manufacturer. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item
Will the 1/2 in Grade 80 alloy chain fit my existing 3/4 in inside-width master links?
Yes, each link has a 3/4 in inside width, so it matches fittings made for that dimension.
How can I verify the 12,000 lb working load limit is still valid after installation?
Inspect every link for stretch, nicks or corrosion; measure inside length — it should stay at 1 5/8 in — and confirm the black oxide finish is intact.
Does the 20 ft length come with any hooks or connecting hardware?
No hook is included; you must supply your own Grade 80 compatible hooks or master links separately.
