Marine Open Link (Studless) Anchor Chain – Lightweight Mooring Solution
Specialized Design for Specific Applications
Unlike traditional stud link chains, our marine open link anchor chain offers a lightweight alternative for vessels where reduced weight is prioritized over maximum strength. While not typically used for primary anchoring, these chains serve important roles in:
-
Temporary mooring systems
-
Light craft and workboats
-
Secondary marine applications
-
Specialized industrial uses
Key Characteristics:
✔ 15-20% lighter than equivalent stud link chains
✔ Easier handling and storage
✔ Compatible with larger shackles without end links
✔ Cost-effective solution for non-critical applications
