Create a durable header system with little cost and maximum visibility. Gripper fins firmly hold rigid signs up to 16 inches tall in header “flush” position. The attached base is designed to fit into most standard gondola uprights. Use two sign holder ends per graphic - a left end and a right end (sold separately). Use a center sign holder to join in-line graphics that are great for eye-catching product and category branding. Removable and reusable. No assembly required. Patented & Patentmore
