Towing chain 70

carbon steelhigh-strengthfor heavy loads

Introduction
Grade 70 Transport Chain is designed for load securement in the transportation sector. It typically provides about 20% higher working load limit compared with High Test (Grade 43) chain. Also referred to as Transport Chain, System 7 or Spectrum 7. Grade 70 Transport Chain is NOT approved for overhead lifting.
Grade 70 is a heat‑treated, high‑strength chain commonly used for tow and binder applications across agriculture, construction, industrial, trucking and forestry sectors.
All Grade 70 Transport Chain is 100% proof tested. Certificates are available free of charge upon request at the time of order placement.
