Color-Keyed Compression System

The Color-Keyed® compression system ensures a proper crimp onto the conductor by matching the right connector to the right tool and die, using a color-coding system that was developed and introduced to the industry by Thomas & Betts. When using the Color-Keyed compression system with our Blackburn® line of compression connectors, the installer can count on a reliable, high-quality connection.


Product Updates

  • We have successfully completed testing and received a UL Listing to allow Burndy, Milwaukee, and Greenlee tools with our dies to provide LISTED crimps with our Color-Keyed® connectors.


Stranded Wire Termination; The precision-hardened steel dies used by the Color-Keyed system exert tremendous, controlled pressure on the connector, forming the strands and connector into a solid mass.

Verifiable and Inspectable: During compression, a die code embossed onto the Color-Keyed connector makes it easy for inspectors to compare the finished crimp with the die table to verify correct termination.

Shure-Stake® Crimp Mechanism: The Shure-Stake crimp mechanism eliminates guesswork and produces proper terminations every time.
