Bradylink® solid color warning posts are made of colourful polystyrene and polyethylene and are a decorative alternative to metal posts. Posts are non-conductive so can be safely used in electrically hazardous areas. Unlike metal posts, Bradylink® warning posts are non-rusting. Hollow base can be filled with sand for more stable application. Large C-hook holds chain in place on large posts and can be used open or closed for greater security.
