Engineers, maintenance technicians, and serious DIY builders who work around moisture, chemicals, food-grade environments, or outdoor exposure need a chain that holds up without constant re-lubrication or replacement. These duplex roller chains are manufactured to ISO\/BS standards in A2\/304 stainless steel, giving you the corrosion resistance of stainless with the mechanical strength of a precision roller chain.\u003c\/p\u003e\n    \u003cp\u003eEach length is 1.524 m (60 inches \/ 5 ft) of duplex (double-strand) roller chain. Available sizes span 06B-2, 08A-2, 08B-2, 10A-2, 12A-2, 16A-2, 20A-2, and 24A-2 — covering pitch ranges from approximately 9.525 mm (3\/8 in) for 06B up to 38.1 mm (1½ in) for 24A. Inner width, roller diameter, and breaking load vary by size; refer to the variant selector for the specification that matches your sprocket.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include food-processing conveyor lines where hygiene and washdown resistance are critical, marine and coastal machinery exposed to salt air, pharmaceutical or chemical plant drives requiring non-reactive hardware, and outdoor agricultural or garden equipment where weather resistance extends service life.
