All of our transport chain is made to NACM (National Association of Chain Manufacturers) specifications. Our chains and binders are in stock and ready for delivery. We carry transport chain in drums or single chain assemblies, and we can also build custom cut chain assemblies to your specifications. Give our our team of product experts a call at 866-348-3473 for help or to place an order.

Grade 70 Transport Chain

Transport chains are high strength chains used in applications where much strength is needed yet the task served is rather straightforward. Sometimes referred to as grade 70 binder chain, cargo chain, high-tensile chain, or trucking chain, this heavy-duty chain is designed for cargo control and tie down applications. Grade 70 chain is never to be used for overhead lifting. Drums of transport chain are available in lengths of 550’, 400’, and 200’, as well as custom-cut chain assemblies and chain tie downs.

When to use Grade 70 Chain

When you need heavy chain to secure large loads grade 70 chain is the best choice. With the most efficient weight-to-strength ratio that comes from drop forging and heat treating, this truck chain allows you peace of mind that your load will be secured in place against sudden stops or tight turns where another transport chain could fail. Grade 70 chain and grade 70 chain hooks can be easily identified by their yellow zinc chromate finish and either 7, 70, or 700 embossed into the surface. Grade 70 chain strength is mandatory for auto transport chains, flatbed chains, heavy equipment chains, tractor tie downs, and log transport chains.

Log Chain

Grade 70 transport chain can be used as logging chain, however standard log chains rate at grade 43. Grade 70 chain is designed for tie-down use only, but will work for any logging operation. High test log chains are typically used for securement, binding, construction, logging, and agriculture, and our grade 70 transport chain is suitable for all of the above.

Hooks for Transport Chain

There are three common types of hooks used for grade 70 transport chain.
  • Clevis Grab Hook
    A shallow throat opening allows for easy and secure connections.
  • Clevis Slip Hook
    Also referred to as a sling hook, is durable and features a wider throat than the clevis grab hooks.These hooks can be attached easily to chains, and allow more versatility within your tie down assembly.
  • Clevis Slip Hook with Safety Latch
    Features a wider throat than a clevis grab hook; designed with a safety latch over the wide throat of the hook to ensure the chain is held in place.

Chain Binder or Load Binder

These two terms are used interchangeably. A chain tensioning device used to bind, clamp, anchor or tie down large cargo loads for transport is what a binder is. The two styles of binders we carry include a ratchet binder and a lever binder.
  • Ratchet Binder
    Also called a ratchet chain or ratchet load binder, this device uses a ratcheting action to tension chain and secure cargo. A ratchet binder consists of a ratchet handle and two tension hooks on each end.
  • Lever Binder
    Also called a snap binder, lever chain or lever load binder. Chain-tensioning device uses a leverage action to tighten and secure loads. With a tension hook on each end, this binder requires more strength to tighten than ratchet binders.
For more information on the differences between ratchet binders and lever binders, see our blog post: Chain Binders .

How Do I Choose a Lever Binder/Ratchet Binder?

When ordering lever binders or ratchet binders you will find that each size is determined with two measurements. There are two main grades of chain for tie-down applications, Grade 43 high test chain is used for stationary, non-transport tie downs and Grade 70 transport chain is for objects being transported on a flatbed or other moving vehicle. Each binder can be used with either size of equipment chain for the appropriate application, but since the different grades have different load limits each binder will be marked with the appropriate chain dimensions for both types of chain for proper performance. The first measurement (smaller) identifies the Grade 70 chain dimension, the second measurement (larger) identifies the Grade 43 chain size required.

Example: 5/16" - 3/8" Lever Binders; the 5/16" specifies the chain binder can be used with 5/16" Grade 70 Transport Chain or it can be used with 3/8" Grade 43 High Test Chain (logging chain.) Small load binders can technically be used for both 5/16" or 3/8" chain in either grade, but if you pair this lever binder with 3/8" Grade 70 transport chain the binder will be weaker than the chain, making the binder the weakest part of the assembly. If you are working with 3/8" Grade 70 chain, the best option would be to pair it with a 3/8" - 1/2" Chain Binder so that the chain and binder are of equal strength. When choosing what grades of chain will go with what binders, be sure to consider both specifications.

How is Chain Grade Measured?

Chain grades are specified by the NACM (National Association of Chain Manufacturers) and the ASTM (American Society for Testing and Materials) standards that define the dimensional, mechanical, and compositional requirements that determine the proof of the steel, minimum breaking force required, elongation, etc. The combination of these measures determines the working load limit that each heavy duty chain can handle before risk of breakage. These factors are tested in a laboratory setting to ensure chain load capacity. Grade 43 chain, also known as High Test Chain, is a mid-grade cargo chain with a working load limit of 5,400 lbs for 1/2" chain. Grade 70, referred to as Transport Chain, is top level of heavy chain with a working load limit as high as 11,300 lbs of cargo for 1/2" chain.

Chain suppliers are required to clearly mark 5/16’’ and 3/8’’ chain links with their grade within 1 foot intervals along the truck chains, and within 3 foot intervals for ½” chain. This is to ensure easy identification and promote safety. It is very important to use the right heavy duty chain for the load you are transporting and these rules are DOT. enforced.

Shipping Notes

Please keep in mind that chain binders and transport chains are heavy. Shipping rates may be reduced when overall weight reaches 200 pounds. We do offer FREE Shipping on orders of $2,000 or more. Contact our sales team for information about contract and volume pricing: 866-348-3473.
