20mm Fully Enclosed Nylon Drag Chain - Dust-Proof Cable Carrier

The 20mm fully enclosed nylon drag chain is a premium cable management solution featuring seamless top and bottom cover plates to block 100% of external debris, also widely searched as 20mm plastic cable chain or 20mm cable drag chain; unlike standard open type cable and hose carriers, this fully covered design ensures zero dust or metal shavings enter the inner cable cavity, perfectly addressing the pain points of CNC machining centers ,laser cutting machine and automated production lines.

Crafted from high-grade engineering PA66 nylon (not inferior recycled plastics), this 20mm closed drag chain delivers exceptional wear resistance, oil resistance, and a wide operating temperature range from -40°C to +130°C; the 20mm inner height accommodates max cables diameters 18mm, while the outer dimensions remain compact for tight machinery layouts; despite its premium nylon build, we offer it at a highly competitive factory-direct price, making it the most cost-effective choice for small to medium-sized automation projects.

Ideal for cnc woodworking routers, laser cutters, and robotic arms where dust contamination is a major concern; for looking for a version with easier cable access, please check our 20mm Bridge Nylon Drag Chain
