Utilizing patented push-in technology, the unique design provides a crimp-free, solderless butt splice making applications easier and faster. The 2-port model supports a wide range of either stranded or solid wires, allowing one connector to cover the same wire range as three traditional butt splices. The end-to-end connection of SpliceLine™ is a great solution for today’s pre-fab operations and also makes it perfect for lengthening short wires in tight spaces. It easily passes through 1/2 inch knockouts and the transparent polycarbonate allows for visual inspection, assuring a secure connection every time.
