FAQ
What crimping tool is required for this 1 AWG compression splice?
Use a 12-ton U-groove compression tool with the index-37 (green) die for 1 AWG copper. Crimp from the centre outward. Verify die compatibility with the 0.500″ outer diameter.
Can I use this connector for aluminum conductors?
No. This compression splice is specified for copper conductors only. For aluminum conductors, specify a connector rated for aluminum or CU/AL applications.
