The Studless Anchor Chain (also known as Open Link Anchor Chain) is a marine-grade anchor chain designed for vessels and offshore applications where reliable anchoring performance and ease of handling are essential. Unlike stud link chains, the open link design has no crossbar inside each link, making it lighter, more flexible, and easier to handle, store, and deploy.
Available in diameters from 12.5mm to 65mm and grades U2 (CM490) and U3 (CM690), this chain meets the requirements of a wide range of marine anchoring and mooring applications.
Self-Colored Finish – Quality Without Compromise
This chain is supplied in self-colored (bare steel) finish – no paint, no coating, no masking.
Why self-colored?
The self-colored finish is the truest reflection of product quality. Unlike black painted or galvanized chains where surface coatings can conceal surface imperfections, the bare steel finish reveals the actual condition of the
material – every weld, every surface finish, every detail is visible and verifiable.
In the marine industry, self-colored chains are often specified for applications where quality verification is critical. Without coating to hide inconsistencies, you see exactly what you get – consistent weld quality, proper heat treatment, and uniform material integrity.
