Description
Galvanised S-shaped chain connecting link 4 mm – rated load 20 kg

The manufacturer's S-shaped chain connecting link is a reliable piece of chain hardware designed for quickly joining sections of chain. Made of galvanised-coated steel, it provides effective protection against corrosion in typical operating conditions. Fitting is simple and requires no specialist tools — the chain is hooked onto the open ends of the link, which are then closed with combination pliers, giving a secure and durable connection. The S shape holds both sections of chain firmly in place under load, while the compact design has no significant effect on the weight of the whole assembly.
Advantages of the S-shaped chain connecting link
- Quick joining of chain sections without welding or specialist equipment
- The galvanised surface protects against corrosion and extends the service life of the connection
- Lightweight, compact design that does not weigh down the chain
- Consistent dimensions ensure a good fit with standard chains
- Versatile use in technical installations, fencing and suspension systems
