Preweld Strip Heaters are made with a cast aluminum shoe and a flat cover to heat your steel application to appropriate preweld and postweld temperatures. They are designed with hanging slots so you can drive a stud and hold them in place. Each strip heater has a 15' input cord with a 15MP3 male connector that plugs into the power streamer. They come in 4 different sizes and can be ordered in any combination to handle your specific applications.
