How to Determine Chain Binder Size

Mar 30th 2026

Selecting the correct chain binder size ensures safe cargo securement, proper tensioning, and compliance with transport standards. This guide walks you through exactly how to match your binder to your chain, your load, and your application.

Quick Answer

Match the binder size to your chain size (e.g., 3/8" chain = 3/8" binder)
Use binders designed for transport chain (commonly Grade 70)
Select ratchet or lever style based on control vs speed
Ensure your full tie-down system is appropriate for the load

Real-world examples:

Skid steer or compact equipment → 3/8" Grade 70 chain + 3/8" ratchet binder
Light-duty loads → 5/16" chain + matching binder
Large machinery → 1/2" chain + heavy-duty binder

What Is a Chain Binder?

A chain binder (also called a load binder) is used to tighten transport chain and secure cargo during transport. It applies tension to remove slack and prevent load movement on trailers.

How to Determine the Right Chain Binder Size

Identify chain size (5/16", 3/8", 1/2" are most common)
Confirm chain grade (Grade 70 is standard for transport)
Match binder size to chain
Select binder type (ratchet or lever)
Verify your full securement setup

Common Chain Binder Size Chart

Chain Size	Typical Use	Recommended Binder
5/16"	Light equipment	5/16" binder
3/8"	Most common heavy equipment	3/8" binder
1/2"	Large loads	1/2" binder

Ratchet vs Lever Chain Binders

Ratchet Binders

Controlled tensioning
Safer and more precise
Best for repeated adjustments

Lever Binders

Faster to use
Simple design
Requires proper handling

Understanding Grade 70 Transport Chain

Grade 70 chain is designed for cargo securement and is commonly used with load binders. It provides the strength needed for transport applications and is available in multiple sizes.

Important: Grade 70 chain is for transport securement only — not overhead lifting.

If your application involves overhead lifting, you should use alloy lifting chain such as Grade 80 or Grade 100. View lifting chain options here.

Frequently Asked Questions

How do I choose the right chain binder size?

Match the binder size to your chain size and ensure it is designed for your application.

What is the most common chain binder size?

3/8" is one of the most commonly used sizes for transport chain and binders.

Are ratchet binders safer than lever binders?

Ratchet binders provide more controlled tensioning, while lever binders are faster but require careful handling.

Can I use Grade 70 chain for lifting?

No. Grade 70 chain is for transport securement only. Use alloy lifting chain for lifting applications.

What is the difference between transport chain and lifting chain?

Transport chain (Grade 70) is used with binders for cargo securement. Lifting chain (Grade 80/100/120) is designed for overhead lifting applications.
