Thermal-Flex Single-Ended Incoloy Rail Heaters provide optimum heat at the point of switch.  The single-ended design simplifies installation by bringing both lead wires out to a central point for termination.  This design further simplifies system wiring, especially when crib or ballast heating is used, by locating all component wiring at the power switch point.  The rail heater’s small diameter tube slides easily behind track braces, and our spring track clips hold everything in place allowing for quicker installation and removal, and more importantly, eliminating the need for rail drilling.
