This FlexChannel clip-in ticket molding strip is easy to install. The flexible back leg is designed to fit 1.16" to 1.23"H price channels. A key feature to the molding is the roof that helps keep dust and debris out of the window. A clear, flexible window allows price tickets to be visible at all times yet stay protected.
