Acco Peerless Grade 43 High Test Chain: Strength You Can Depend On
When a job demands a chain that delivers more pull than standard proof coil or BBB chain without the bulk and weight of an alloy grade, Acco Peerless Chain has long been the benchmark. Their ACCO® G43 Domestic High Test line — part of the broader High Test 40/43 chain category — represents a refined solution for mariners, farmers, riggers, and tradespeople who need a trusted, domestically manufactured chain they can stake a load on.
What Is Grade 43 High Test Chain?
Grade 43 chain — sometimes referred to as High Test (HT) chain and historically marked under the Grade 40 designation — is a step above everyday utility chain. Its working load limit is approximately twice that of BBB or proof coil chain of comparable size, making it a favorite where space and weight matter but strength cannot be compromised. High Test 40/43 chain is commonly used for container securement, logging, farming, towing, and marine applications across a wide range of industries.
The ACCO® G43 Difference
Acco Peerless Chain brings several standout engineering choices to their G43 product line that set it apart from generic high test offerings:
- ISO Short-Link Design: The ACCO® G43 features an ISO short-link geometry that makes the chain more flexible and ideally suited as a windlass chain and less likely to tangle in the chain locker. The calibrated links are also designed to fit most windlass wildcats with an "HT" designation, smoothing out the anchor-setting process considerably.
- High-Tensile Carbon Steel Construction: Manufactured from high-tensile carbon steel to both NACM and ISO standards, the G43 chain delivers a superior strength-to-weight ratio versus proof coil alternatives of the same diameter.
- Hot-Dip Galvanized Finish: In a process that first shot-peens the chain before galvanizing, the extra-thick hot-dip galvanized coating provides superior corrosion protection and is recommended for all marine applications. The chain even carries a two-year guarantee against rusting.
- Made in the USA: Peerless ACCO® G43 windlass chain is made in the USA, an important credential for buyers who prioritize domestic manufacturing standards and quality consistency.
- General Utility Versatility: Beyond marine use, this chain is a proven workhorse for log chain, cargo lashing, pipeline hanging, tailgate, guard rail, tow, and switch chain applications on farms and job sites.
Choosing the Right Size
Peerless offers the ACCO® G43 High Test chain in a range of diameters — from 1/4" up through larger sizes — to suit everything from lightweight buoy lines to heavy anchor rodes on offshore vessels. When selecting a size, always confirm compatibility with your windlass manufacturer's specifications, as link dimensions vary by diameter. The chain carries the "G4" hallmark stamp on its links, making grade identification easy in the field. Note that, like all High Test chain, it is not approved for overhead lifting.
Whether you're outfitting a new anchor system, replacing a worn tow chain, or securing cargo on a trailer, the Acco Peerless Grade 43 High Test chain lineup offers the corrosion resistance, documented strength ratings, and domestic quality control that demanding applications require.
