3M Performance Plus Scotchlok wire connectors are a two-wire connector that is engineered and designed to allow for greater wire capacity. Each Performance Plus wire connector will replace two standard wing/nut connectors. The connector can complete the job that used to take 8 connector sizes to accomplish. These 3M Scotchlock connectors have flexible skirts that provide protection and readily bend to conform and fit in tight places. 3M Performance Plus wire nuts are for jobs requiring multiple connections as they provide an easy and painless installation process with better resulting connectivity.
