Expansion Elements
Our standard Electrobar FS expansion elements come in 15' lengths and include our PVC conductor bar cover and power feed covers with UV protection. Expansions are completely pre-assembled, requiring only proper gap setting by the installer (refer to technical bulletin for gap setting data). Expansions may be installed in operating environments up to 160 degrees Fahrenheit.
