Our Anti-Rotational Clips (ARC) are manufactured from AISI 304 Stainless Steel and provide a simple, economical and speedy solution for installing signs manufactured with ALL SIGN SYSTEMS support channel. To install a sign, insert and slide the 'foot' of the bracket into the sign's ALL SIGN SYSTEMS channel, and twist the clip through 90 degrees. The other end of the clip is then secured by the bolt. Raised pips on the inner face of these one-piece clips help prevent sign rotation. Each bracket is supplied with a M8 LIP-LOK bolt assembly.
