Don't let your rope lights become a safety hazard! These FlexTec rope light end caps are for use with 5/8-inch rope lights. Used to seal off the cut segments of rope light, they protect the exposed wires inside from shorting out and protect you from a possible electrical shock. While these end caps are water resistant, they should be used with a sealant to make them fully waterproof, giving you complete confidence when using rope light outdoors.
