Meaning of Grade 70 Chains & Binders

Grade 70 chains are chain binders. Also called trucker chains, boomer chains, or transport chains, chain binders are an option for securing heavy loads. These chains are made from high strength carbon steel, and they can safely secure a higher working load than lower grade chains. These chains tend to have a maximum working load limit of 11,300 lbs. That said, it’s vital to check the specific, listed WLL of every individual product before you buy it.

A chain’s working load limit is about 1/3rd of its breaking strength. So the chain breaking strength of a ½ inch thick G70 is 33,900 lbs.

This chart form the National Association of Chain Manufacturers demonstrates the WLL of different thicknesses of Grade 70 chains.

Grade 70 chains are painted with yellow chromate, a color mandated by the Department of Transportation so they’re easy to recognize. A stamp indicating the chain strength much be embossed along the length of the chain periodically, with stamps no further than 1 foot apart. Grade 70 chains also come with various end fittings; you can even get a chain with a clevis hook.

Advantages of Having G70 Chains

There are quite a few benefits when you choose grade 70 as your load binder chain.

  • High working load limit -

    G70 chains are suitable for much heavier loads than winch straps and other type of securement.
  • Durability -

    G70 chains are durable and long lasting.
  • Corrosion resistance-

    The gold chromate coating makes G70 chains resistant to rust and other kinds of corrosion.
  • Lightweight carbon steel -

    G70 chains are made of carbon steel, which weighs less than stainless steel and is easier to carry.

Where can I use G70 chains?

G70 chains are typically used to secure lumber or steel loads, but can be used to secure almost any load below the working weight limit. This grade is the most popular among the variety of chains and binders for flatbed trucks, because it weighs less than higher grade chains while still staying strong and versatile enough for most transport.

G70 chains are also used for towing and lashing.

What are my G70 chain options?

When choosing among G70 chain options to find what works for you, there are three factors to consider: chain length, binder type, and hook type.

1. Chain length options

Choose from a wide variety of chain lengths, or custom order the size that fits your load.

2. Binder Options

At Mytee Products, we offer a selection of chain binders, which fall into three broad categories.

  • Ratchet binders - Ratchet chain binders increase the tension in a chain until it’s taut, using a twisting (ratcheting) mechanism. Since the ratchet handle doesn’t store energy, it won’t abruptly recoil.
  • Lever binders - These binders are sometimes also called snap chain binders. Lever binders are easier to use than ratchet binders because their design is simpler and you can tighten them fast. However, they have a higher risk of accidental recoil.
  • Recoilless Lever binders - Recoilless chain binders utilize a lever mechanism, but they mitigate the risk of recoil. The design allows the center cam to move independently, breaking up the store energy.

3. Hook Options

The National Association of Chain Manufacturers (NACM) maintains standards and specifications to ensure that every transport chain hook is safe, effectively keeping chains connected and loads tied down. At Mytee Products, 100% of our hook options meet NACM’s high standards. This means our hooks pass a “breaking force” test, and each one is capable of “withstanding breaking force loads.”

Our hook options include:

  • Slip hooks - These hooks are forged from strong, low0alloy carbon steel.
  • Clevis hooks - A clevis hook incorporates a lightweight, low-alloy carbon-steel latch for extra security.
  • Heavy duty towing hooks - These hooks are designed to be welded on and are slightly heavier.
