This is a Peerless 1/2" V10 Coupling Link (model WLK13). It's a Grade 100 link with a blue finish, made in Italy. The working load limit (WLL) is 15,000 lbs. It is used but in good condition.

This robust coupling link is suitable for heavy-duty applications where a secure and strong connection is essential. The blue coating shows some wear, and the pin has surface rust, but it remains fully functional.
