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.

Grade 43 Chain—50% stronger than Grade 30 chain, this chain is great for towing as well as quickly securing and releasing large loads when logging.

Grade 70 Chain—Secure vehicles, machinery, and other loads on trailers and trucks for safe transportation. It's approximately 20% stronger than Grade 43 chain and 60% stronger than Grade 30 chain. Also known as transport chain, it meets D.O.T. standards for load securement.

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.

Zinc-Yellow-Chromate-Plated Steel—Won't scratch or wear away as fast as clear zinc plating and resists occasional moisture. The distinctive golden color confirms this chain is compliant with Department of Transportation (DOT) regulations.

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.

Extra Heavy Duty Chain for Lifting

Lift, hoist, and rig heavy equipment, vehicles, containers, and more with the strongest chain we offer. This chain is graded by weight capacity, so you can pick the best option whether you're hauling a bulldozer or unloading cargo from a ship. 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: Never use chain to lift people or items over people.

Grade 80 Chain—Your go-to option for most lifting jobs. Rig and lift industrial vehicles, heavy machinery, and shipping containers with this chain.

Black Painted Steel—Best for dry environments as paint may chip and corrode over time.

Wear Gauges

Measure the maximum amount of wear allowed by OSHA on links of Grade 80 or 100 steel chain. If you can insert the gauge over any part of the link, you should take the chain out of service.
