Choose the Correct Fit
Match the die or adapter to the crimper, conductor and connector using the manufacturer’s compatibility chart.
A matching wire size alone does not establish connector compatibility. Follow the applicable tool and connector instructions.
Installation & Care
Inspect the die surfaces and identification markings before use. Keep the mating surfaces clean and free of damage.
Store the accessory clean and dry after use. Follow the crimper manufacturer’s maintenance and replacement guidance.
