FAQ
Q: What is the difference between DIN 763 and DIN 766?
A: The primary difference is the link length. DIN 763 is a Long Link chain (internal length $\approx$ $4.5 \times$ diameter), while DIN 766 is a Short Link chain. DIN 763 is used for general tying and fencing, whereas DIN 766 is often used for windlasses and marine anchors.
Q: Can I get a customized length?
A: Yes, we provide customized cutting services and various bulk packaging options to suit your retail or industrial needs.
