The through connector for plug-in is the ideal product for connecting wires in the smallest spaces. There are many applications for the through connector, whether it's extending a short wire in a flush-mounted box, lengthening entire cables, or repairing damaged lines. With the through connector, you can easily, quickly, and safely connect electrical wires in tight spaces – and the best part: it's completely tool-free. In case of repairs, the connector can also be used in flush-mounted applications with a suitable heat shrink tubing, thanks to its maintenance-free spring technology, making it a true problem solver and an indispensable helper. Its short and compact design allows multiple through connectors to be arranged in a space-saving manner.
