Proximity seating a problem? 2/90 introduces RESERVED Seat Barrier, a better solution than paper messages to ensure the safety of those in your care. Reserved not only informs people the seat is unavailable but prevents them from sitting. The sign is constructed of 3MM expanded PVC with direct print copy. It installs easily with an adjustable hook and loop strap. Strategically place RESERVED seat barriers creating a visual and physical barricade to eliminate close seating in public.
