FMCSR 393 Chain & Binder Inspection
Pass Level I CVSA inspections. Inspect transport chains for link stretching, verify embossed manufacturer grade markings, audit ratchet binder pawls, and replace cracked edge protectors.
Chain Grade Markings
Chains without legible embossed markings (G7, G8, or G10) default to Grade 30 proof coil rating (1/3 the WLL), triggering an instant DOT tie-down deficit citation.
Stretched / Gouged Links
Any chain link showing greater than 10% diameter reduction from gouging, bending, twisting, or stretching must be cut and removed from flatbed service immediately.
Ratchet Pawl & Barrel
Inspect binder screw threads for stripping. Pawls must lock into teeth completely. Prohibit cheater pipes on lever binders due to severe driver recoil fractures.
Beveled Edge Armor
Steel coils have razor-sharp slit edges that crush chain links or shear straps. Heavy steel or molded polyurethane protectors distribute downforce across coil radiuses.
Exspeedite Coil Securement Pre-Departure Gate Pass
Shippers require signed confirmation that drivers inspected all binders after the first 50 miles of transit as mandated by 49 CFR § 392.9.
