Switchblade Movable Point Frog Heating – Type FSM

Depending on location requirements, the SwitchBlade® heater is positioned within the slots of the wing rail braces to allow the heater to slide onto the top of the wing rail base. SwitchBlade® heaters may also be necessary in the four channels welded onto the bottom of the base plate just below the point area. If the frog is of a different design a retrofit may be required, contact factory for more information on Type
SMR.
