I have for sale two conical-fermenter.com 1.5" tri-clamp to nsp thread adapters for installing water heater elements. Included is 1 4500 watt Richmond brand element, two 1.5" tri-clamps, two 1.5" ferrule and silicone gaskets. Also I can throw in some 10-3 SO cord. The one measures 80" and the other measures 11 foot, note note sure about the twist lock as it is rated for 125 volt application still the 10-3 SO cord will work nicely for feeding 240v elements. $50 plus shipping, note I have some other complementary items posted.
