3/8" Anti-Theft Steel Sign Rivets - XDR387805Z

These 3/8" Anti-Theft Steel Sign Rivets are designed to be used with Telespar square sign posts. They're perfect to use with signs that are repeatedly stolen. Simply line up your sign holes with your sign post, slide the rivet into place through both the sign and post holes and tap the pin of the rivet with a hammer. The back of the rivet will expand inside the post, making it very difficult for vandals to remove the sign.
