The grade of a chain refers to its tensile strength. The higher the grade, the stronger the chain will be. What is Safe Working Load? The safe working load of a chain is the maximum working load designated by the manufacturer. It represents a load that is less than the minimum load that would make a chain fail or break to ensure the user's safety when using the product. It is calculated by dividing the load at which the chain would fail by a certain safety factor specified by the manufacturer. *Please see the specifications of each rope product for its safe working load. Machine Chain Made of low carbon steel, this chain is electronically welded and is not heat-treated. It has shorter links that make it very flexible Pros: Greater flexibility than other general use chain. Cons: Not intended for heavy weight loads. Common Uses: Guard rails, tailgate chains, door chain, playground equipment. SHOP MACHINE CHAIN Machine Twist Chain Made of low carbon steel, this chain is electronically welded and is not heat-treated. It has shorter links that make it very flexible. Links are twisted to allow chain to lay flat. Pros: Will lay flat unlike other styles of chain. Cons: Not intended for heavy weight loads. Common Uses: Pet chains, playground equipment. SHOP MACHINE TWIST CHAIN Passing Link Chain Made of low carbon steel, this chain is electronically welded and is not heat-treated. A general utility chain with a wide link design that allows the links to pass through one another which reduces the chance of tangling and kinking. Pros: Less chance of kinks or tangling. Cons: Not intended for heavy-duty use. Common Uses: Gates, farm equipment. SHOP PASSING LINK CHAIN Proof Coil Chain Excellent general purpose, low carbon steel, utility chain Pros: Cost effective, general purpose chain. Cons: Lower strength than higher grade chain. Common Uses: Pulling stumps, truck tailgates, guard rails. SHOP PROOF COIL CHAIN Sash Chain Stamped, flat-link chain that runs smoothly over pulleys. It is made from low carbon steel and is not heat treated. Pros: Lays flat and runs smoothly over pulleys. Cons: Low strength chain. Common Uses: Counterbalance chain for double hung windows, arc lamps, pet chains. SHOP SASH CHAIN Transport Chain Made of heat-treated, high carbon steel, this chain offers superior strength and wear resistance. It is lightweight despite its strength and easy to handle. Pros: Superior strength and wear resistance. Cons: More expensive than lower grade chain. Common Uses: Load binding in the trucking industry. SHOP TRANSPORT CHAIN Construction Plastic Coated? Available Sizes Applications 7x7 Yes 3/32" Tensioning, security cables, cable railings No 3/16" Tensioning, security cables, cable railings 7x19 No 1/8”, 1/4", 5/16”, 3/8” General utility, security cables, winch cables Cable Construction Cable is constructed of special strength similar size wire wound together to make a strand. These individual strands are wound together to make a cable or wire rope. Cable is specified by the number of strands, times the number of wires in each strand. For example, 7 x 19 means that the cable has seven (7) strands and there are nineteen (19) wires in each strand. Cable Materials The material of the individual wires that make up a strand will affect the properties of your cable. Galvanized: Slightly stronger than stainless steel, but less corrosion resistant. Stainless Steel: Similar in strength to galvanized steel and corrosion resistant. More expensive Galvanized Plastic Coated: Superior protection against the elements, can last longer than a non-coated cable. Does not offer good abrasion resistance. How to Measure Cable Diameter Correct Incorrect 7X7 Cable Cable is made up of 7 strands. Each strand consists of 7 wires. Pros: Cost effective. Cons: Rigid in larger diameters. Common Uses: Tensioning, security cables, cable railings. SHOP 7x7 CABLE 7X19 Cable Cable is made up of 7 strands. Each strand consists of 19 wires. Pros: Superior strength and flexibility. Cons: Rigid in larger diameters. Common Uses: Tensioning, security cables, cable railings. SHOP 7x19 CABLE WARNING: Do not exceed safe working load. Do not use for hoisting or overhead lifting Do not use if rope is visibly worn or distorted. Misuse can result in serious injury, property damage or death.
