10A 4mm TP81 Insulation Piercing Test Clip Set - Black and Red - 

FLUKE TP81 is an insulation piercing clip set which connects to banana jack leads. Stainless steel probe pierces insulation on 14, 16 and 18 gauge wire. You control needle depth to minimize insulation damage. Essential for use under hood or under dash. Use it on fuel injectors or sensors while providing complete insulation to grounding due to design. Banana jack accepts all DMM and banana jack leads. Non-rotating banana jack prevents leads from tangling, allowing you to tighten/loosen clamp while still connected to the test lead.
