  • Publication number: 20050023366
    Abstract: The extruded rubber boot is wrapped around the rail before the rail is placed in the ground. The boot provides electrical and mechanical isolation of the metal rail from the concrete of the pavement. The boot profile is configured with a double-wall column, which, when hammered in, becomes tightly wedged between the head and the base of the rail. Nothing else (such as adhesive tape wrapped around the boot) is needed in order to hold the boot to the rail during assembly and installation of the rail and pavement.
