Made in China

This Osculati hot-galvanized calibrated chain is a Grade 70 high-resistance type engineered to deliver greater mechanical strength per unit diameter than standard anchor chain. Its higher grade allows the use of smaller, lighter chain while maintaining equivalent or superior holding performance.

Installation guide

Verify gypsy compatibility

Check that your windlass gypsy matches the chain's calibration (DIN766 or ISO) and link dimensions (P × B mm). Mismatched gypsies cause skipping under load.

Pre-feed the chain

Lay the chain out straight in a clean area to avoid kinks. Inspect every metre for defects, weld flash or burrs before loading.

Connect to the rope rode

Use a chain-to-rope splice or a calibrated swivel (e.g. Osculati 01.230) sized to match the chain. Ensure the connection passes smoothly through the gypsy.

Load into the locker

Feed the chain through the bow roller and gypsy with the windlass at low speed. Allow it to fall freely into the chain locker — never force it.

Set the bitter end

Secure the bitter end to a strong point in the locker with a nylon line short enough to be cut quickly in an emergency.
