3M™ Performance Plus™ Wire Connectors are designed with a uniquely flexible spring that has generous room for expansion and a strong bite for a secure connection. Because of their increased wire range, just three Performance Plus wire connectors handle the work of eight standard connectors. And the flexible skirt helps prevent copper exposure for enhanced safety.
