3/8" Grade 70 Chain Extension with Pear Link & Eye Grab Hook — 5,400 lbs WLL

The 3/8" Grade 70 chain extension with pear link and eye grab hook solves the gap problem on chain tie-down assemblies — when the working chain is too short to reach the load anchor point cleanly, or when you need to add reach to an existing assembly without replacing the whole chain. At 5,400 lbs WLL with a 3:1 design factor, this extension maintains a robust safety margin while integrating seamlessly into G70 chain setups.

The pear link provides the connection point between the extension and the main chain assembly. The eye grab hook at the other end gives you a fixed capture point that engages vehicle anchor hardware or trailer D-rings cleanly. A complete, ready-to-use extension — no assembly required.

Why a Chain Extension Instead of a Longer Chain

Chain extensions add reach to an existing assembly without discarding a functional chain. The pear link connects the extension to the main chain, the hook engages the load anchor, and the working length increases by the extension's length — all while staying within the Grade 70 system. Extensions are the right tool when loads vary in position, when anchor points aren't always in the same place, or when an operator keeps a standard chain length on every trailer but occasionally needs a few extra inches to reach.

Note: The complete assembly's WLL is limited to the lowest-rated component in the chain. At 5,400 lbs WLL, this extension is rated below the standard 3/8" G70 hook's 6,600 lbs WLL — size the total assembly accordingly.

Frequently Asked Questions

What is the WLL of the chain extension?

5,400 lbs at a 3:1 design factor. This is the rating for the complete extension assembly — chain, pear link, and eye grab hook. When used as part of a longer chain assembly, the total assembly's WLL is the lower of the main chain WLL and the extension WLL. Size your total tie-down system so that aggregate WLL across all chains meets FMCSA 49 CFR 393.106 requirements for your load.

What is a pear link and how does it work?

A pear link (also called a pear-shaped master link or master link) is an oblong or pear-shaped connecting link that joins two chain components — in this case, the extension chain to your main chain assembly. The larger opening of the pear link makes engagement and disengagement easier than a standard chain link would allow, while maintaining the rated WLL of the assembly. Pear links must be matched in grade and size to the chain components they connect.

Can I use this extension with 5/16" chain?

No. This is a 3/8" chain extension — the pear link and eye hook are sized for 3/8" Grade 70 chain links. Mixing chain sizes in an assembly is not recommended and may prevent proper link engagement at connection points. Use 5/16" extensions with 5/16" chain assemblies only.

Is this DOT compliant for cargo securement?

Yes, when used within its 5,400 lbs WLL rating as part of a properly configured Grade 70 chain assembly for DOT/FMCSA cargo securement. The extension must be accounted for in total aggregate WLL calculations — use its 5,400 lbs WLL (not the main chain's higher WLL) for any assembly that includes this extension.
