Compression Lug and Splice Ratchet Crimpers

The ratchet applies the correct pressure to ensure a complete crimp every time. The dies are built into the rotating head. A reference chart on the tool shows you which one to use when attaching connectors to electrical wire.

This tool also works with 8- to 4/0-gauge battery terminals and heavy duty power lugs (you must use comparable battery terminal settings).

Compression Lug and Splice Crimpers

No dies to buy or change—this tool has settings you adjust for different compression connector sizes. A reference chart on the tool shows you the correct settings, which you adjust with the turn of a single screw. The head has a flat surface for standing the tool up. The handles telescope 13” for increased leverage.

Hydraulic Compression Lug and Splice Crimpers

The most crimping force we offer—these tools have a high-pressure pumping system with a replaceable pressure cartridge that lasts for 10,000 to 12,000 compressions. The head swivels 180°.

Dies are required. The tools accept U-type dies for Alcoa, Burndy, Panduit, T&B, and Blackburn 12-ton tools. We list lug markings for two common manufacturers to help choose the correct die for your compression lug.

Combination Electrical Wire Strippers and Crimpers

Strip wire and crimp connectors with one tool.

Tools with a plier nose are useful for pulling and looping wire.

Tools with a reference chart are marked with wire gauge and metric sizes.

Tools with a voltage detector safely test for AC voltage without contacting live wires. Light and sound indicators alert you when over 50 volts AC is detected. The detector is attached to the tool’s handle; remove it from the handle to use it on its own.
