These duplex roller chain connecting links are designed for engineers, maintenance technicians, and serious DIYers who need a dependable, drop-in solution across a wide range of chain sizes — from compact 06B up to heavy-duty 40B.\u003c\/p\u003e\n    \u003cp\u003eEach connecting link is manufactured from carbon steel with a zinc-plated or natural steel finish, providing solid corrosion resistance for typical workshop and light industrial environments. The duplex (double-strand) configuration means each link spans two parallel roller chain rows, maintaining alignment and load distribution. Available sizes span 06B through 40B (covering both A-series and B-series standards), with pitch dimensions ranging from approximately 9.525 mm (3\/8 in) for 06B up to 50.8 mm (2 in) for 40B.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include agricultural machinery chain drives, industrial conveyor systems requiring duplex roller chain connecting links for repair, power transmission equipment in manufacturing lines, and workshop fabrication projects needing ISO-standard roller chain links. Whether you are replacing a failed link on a grain elevator or assembling a custom drive system, these links deliver consistent fit and function.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e\n    Compatible with ISO 606 \/ BS 228 duplex roller chain in sizes 06B, 06C, 08A, 08B, 10A, 10B, 12A, 12B, 16A, 16B, 20A, 20B, 24A, 24B, 28A, 28B, 32A, 32B, 40A, and 40B.
