This flex-frame sidewalk sign is designed for ease of use and convenience. With a top-loading frame, changing sign inserts is a breeze. Just slide your double-sided 36″ high by 24″ wide sign inserts, which can be up to 3/8″ thick, into the top of the sign frame, and they’ll be held tightly in place. The heavy-gauge steel provides strength and support, while the four durable springs keep your sign swaying, not falling apart, even in high winds. This is a functional, economical sign that allows you to create a professional appearance for both indoor and outdoor displays.
