The Insulation Piercing Hooks provide contact through most insulation barriers on wires so that your testing is kept
simple and efficient. These hooks use a needle to establish accurate contact through insulation.
Expanding upon our already easy-to-use Macro-Hooks, the XJ, XJL and XEL are heavy-duty test connectors that
create positive contact through insulation. We offer the XEP & XEPA, insulation-piercing Micro-hooks
that permit connections in smaller testing applications.
