Anti-Rotational Clips (ARC) are fasteners made from AISI 304 Stainless Steel designed to securely mount signs with Signfix channels onto round Fluted Aluminum or Steel Poles. They are a simple, economical, and fast way to install signs. The ARC clips slide into the Signfix channel on the back of the sign and twist into place to lock it onto the pole. The raised pips on the inside of the clip prevent the sign from rotating. They are sold in boxes of 100 and come with the M8 LIP-LOK bolts needed for installation.
