The best wire connectors do more than fit the application; they also fit your hand, and they feel good to use. At 3M, we design connectors that are as comfortable and easy to use as they are dependable.
For over 30 years, 3M has been designing connectors with the reliability and ease of installation that electricians demand. From the very first 3M Scotchlok insulation displacement connector (IDC) to today's improved models, 3M has always provided connection technology that saves time and money. Our complete line provides a wide range of connector choices. Simply choose the connector that fits your personal preference, as well as the application. We give you plenty of choices. Start with the unique 3M Performance + wire connectors, three connectors replace the traditional seven, and still cover the entire 600-volt copper wire range. The 3M Scotchlok connectors are our original color-coded line of wire connectors designed with the exact features requested most by electricians. 3M wire connectors are durable for regular or low-voltage systems in construction, industrial, maintenance, OEM or irrigation. 3M Highland wire connectors offer an affordable alternative with no compromise t
