30mm Series Plastic Cable Drag Chain - Open Bridge Nylon Carrier

The 30mm inner height plastic cable drag chain series is an open-bridge cable management solution engineered for industrial machinery requiring mid-to-heavy cable payloads. Molded from 100% virgin PA66 engineering nylon—without blended or recycled plastics—this durable series delivers high tensile strength, exceptional wear resistance, and long service life under high-speed reciprocating movement.

Featuring a lightweight open-bridge construction, this plastic cable drag chain allows rapid cable and hose installation, direct visual inspection, and easy routine maintenance without disassembling the entire carrier. The open architecture facilitates maximum heat dissipation, preventing temperature buildup around high-flex power leads and signal wiring. For harsh industrial operating environments where dust, cutting fluids, or hot metal chips pose a risk to wiring, explore our fully sealed 30mm series enclosed drag chain range.
