Bradylink Warning Post Chains are made of colorful polyethylene and are a decorative, rust-free alternative to metal stanchion chains. Chains are color coded to match our Bradylink Warning Posts and have a special link design that prevents kinking. Bradylink Chains are not intended to support heavy objects and are recommended for indoor use only. Package includes chain only (stanchions sold separately). The Bradylink Warning Post System is non-conductive so it can be safely used in electrically hazardous areas.
