This is a replacement electrode with a 15 foot cord for the MegaChlor Chlorine Generator. Simply remove the 4 screws to open the MegaChlor control box, loosen the 4 terminal post screws and remove the old electrode. Replacing the electrode will allow your generator to begin chlorinating again, if your old electrode has been depleted.
The MegaChlor replacement electrode is only compatible with the ControlOMatic MegaChlor power supply.
