Every post-mounted sign needs its connector, and for the banner system this set is it: NeXtrac clips that fasten a banner sign — or any compatible 3/8-inch-thick retail sign panel — onto a Beltrac Tall Partition post. The Banner Signs are the panel, the post is the upright, and these clips join the two. Each clip measures 4 inches, sized to hold a panel securely against the post, and the included Allen wrench makes the set install-ready out of the box. Because the clips grip standard 3/8-inch panels, they serve as general mounting hardware for compatible signage across the post line. SKU 80-BC04/Set.
