The latest series of 3M Scotchlok Insulation Displacement Connectors (IDCs) has kept all that was good about the original connector — the design, the shape, the element technology and the color-coding. Each model, however, also incorporates a full wire range capability, an increased port size that accommodates up to 0.155" (4,0 mm) insulation sizes, double "U" elements and a solvent-resistant plastic construction. Choose from 38 different 3M IDCs to meet a variety of uses, including fluorescent ballast installation and replacement, fixture and appliance wiring, automotive and marine wiring, and control circuit wiring.
