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.

Quick, reliable splices are a snap and a squeeze
For over 50 years, 3M has been designing connectors  
with the reliability and ease of installation that electricians 
demand. From the very first Scotchlok insulation 
displacement connector (IDC) to today’s improved models, 
3M has always provided connection technology that saves 
time and money.
The latest series of IDCs has kept all that was good about 
the original connector — the design, the shape, the element 
technology and the color-coding.
Choose from 38 different 3M IDCs that meet a variety  
of uses, including fluorescent ballast installation and 
replacement, fixture and appliance wiring, automotive  
and marine wiring and control circuit wiring. Whatever the 
application, 3M has the connector to make your job easier.
