S-Line ratchet-style chain load binder for tensioning Grade 43 and Grade 70 transport chain over loaded flatbeds, trailers, and farm equipment. The ratchet handle multiplies hand force through a screw-thread mechanism with a built-in thread safety stop - distinct from a lever-style (snap-bind) load binder, which uses an over-center cam mechanism that snaps closed under spring tension and can release violently if struck. The ratchet style trades a slightly slower tension cycle for a controlled, predictable release - the right pick for higher-WLL chain assemblies and any user new to load binding.

• Working load limit (WLL): 5,400 Lb
• Chain compatibility: 5/16" or 3/8" Grade 43 or Grade 70 transport chain
• Construction: Drop-forged steel body and hooks
• End fittings: Forged steel grab hooks
• Mechanism: Ratchet screw with built-in thread safety stop (prevents over-extension)
• Finish: Red E-coat paint for corrosion resistance and high visibility
• Compliance: Meets or exceeds WSTDA T-6 standards; meets DOT / FMCSA 49 CFR 393.108 securement requirements when paired with Grade 70 chain
• Not for overhead lifting (transport chain securement only)

Tip: The 5/16" - 3/8" chain capacity is the workhorse over-the-road binder size - skid steers, mini excavators, full-size tractors, vehicles (cars, light trucks) on flatbed trailers, large round bales, pallets of building material, and any mid-to-heavy commercial cargo. Pair with the matching Grade 70 transport tow chain (G473 3/8" 6,600 Lb WLL) for a complete cargo securement kit. Always check that the aggregate WLL of your chain-and-binder assembly equals or exceeds half the cargo weight per federal regulations - and add additional securement points so any single failure doesn't release the entire load.
