DuraLatch® Crossbracing with 3 Flags holds any 36" or 48" diamond-shaped DuraLatch Roll-Up Sign. It has three heavy-duty, solid-tip steel posts that the Lift-The-Dot fasteners on the sign straps snap on to. The posts hold sign securely while the straps allow it to expand and contract to stay taut. For storing, crossbracing pivots to form one piece that the roll-up sign wraps around. For use with all WindMaster® Sign Stands.
