About Chain

Find a chain style and capacity that's up to any task, from hanging a 5 lb. light fixture to rigging a 17 ton generator.

Heavy Duty Chain

Bind, tie down and tow loads with this chain. This chain is graded based on weight capacity, so you'll always know exactly how much it can handle. Look for the manufacturer's stamp on each link to confirm the grade.

When using fittings with chain, match the trade size and meet or exceed the chain’s grade to avoid chain damage or failure.

Warning: Not for overhead lifting.

Grade 30 Chain—An economical choice for everyday industrial jobs that require only moderate strength. It's commonly used to create guardrails and to secure loads on farms and construction sites.

Tangle-Resistant Grade 30 Chain—The strongest tangle-resistant chain we offer. Shorter links make this chain easier to coil and less likely to knot when you're trying to store or transport it.

Steel—Best for dry environments since moisture will cause this chain to rust.

Zinc-Plated Steel—A common and economical choice, the zinc plating resists occasional moisture.

Galvanized Steel—A thick coating protects this chain in wet and outdoor environments about as well as 304 stainless steel, but it corrodes when exposed to salt water and chemicals.

Powder-Coated Steel—Powder coating steel gives it a colored finish and a strong barrier against moisture and mild chemicals.

Medium Duty Hammer-Close Ring Links—Not for Lifting

Image of Specification. Front orientation. Contains Annotated, Border, MultipleImages. Ring Links. Medium Duty Hammer-Close Ring Links—Not for Lifting.

Drive the end through the eye using a ball peen hammer and then weld or flatten the extended end to close. Also known as cold shuts, these links are an economical option to join chain links and attach fittings. They must be completely closed to perform at capacity. Never reuse links after they've been closed.

Zinc-Plated Steel—Zinc-plated steel links are mildly corrosion resistant.
