Medium Duty Chain

Construct barriers and hang fixtures such as lighting and storage racks. While it won't hold up the same amount of weight as heavy duty chain, this chain is lighter and easier to carry.

Warning: Not for overhead lifting.

Tangle-Resistant Chain—Unlike other straight-link chain, short, wide links make this chain easier to coil and less likely to knot when you 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.

Twisted-Link Chain

Chain

The links on this chain lie flat against curved or awkwardly shaped loads to secure them tightly.

Warning: Not for overhead lifting.

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.

Lock-Link Chain


Standard Profile	Flat Profile

Operate overhead doors and machinery too heavy for a sash or plumbers' chain. The ends of the chain lock around the connecting link, so it lies flat against chain wheels and sprockets.

Warning: Not for overhead lifting.

Flat Profile—Trimmed links allow this chain to sit closer against a chain wheel or sprocket.

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.

Chain Connectors—Form your chain into a loop on a chain wheel.
