The gripper is designed to quickly and easily attach a banner to the hanger: Just snap up to open, insert sign and snap down to close. Integrated soft gripper fingers hold signs firm. High quality cups with reinforcing rings for added strength and long-term holding power. Please note: Temperature and humidity may cause a suction cup to lose its grip. When applied to a clean, dry, non-porous surface above 40°F (5°C), these cups should have an operating range of -22° to 120°F (-30° to 49°C).
