Pair of red and black test leads with alligator clips and banana plugs, 3.3ft long

Unique-Bargains

Unique-Bargains Alligator Clip to Banana Plug Test Lead Cable 3.3ft Pair

SKU CH-JWNZ-0DATX

Pair of 3.3 ft test leads with alligator clips and 4 mm banana plugs for quick circuit connections

  • 3 ft length gives ample reach for bench work
  • 2 mm wire diameter handles typical lab currents
  • 4 mm banana plugs fit standard multimeter jacks
  • 6 mm alligator opening grips component leads securely
  • Insulated boots protect against accidental shorts

Electrical Test Lead Cable

This pair of alligator-clip-to-banana-plug cables connects bench instruments to components or circuit nodes. The 3.3 ft length suits bench-top work where a fixed power supply or multimeter feeds a prototype. Hobbyists, students and service technicians can hook and unhook points quickly without soldering.

Replaces Improvised Jumper Wires

Loose hook-up wire with stripped ends slips off terminals and risks shorting adjacent pins. These leads add shrouded 4 mm banana plugs and spring-loaded alligator clips rated to 6 mm jaw opening, so connections stay firm during vibration or probe movement. The upgrade is worth it whenever a test setup is rebuilt repeatedly or must survive handling.

Practical Limits of Banana-Plug Interface

The 4 mm plug diameter fits standard laboratory sockets but will not mate with 2 mm or proprietary connectors found on some handheld meters. The 2 mm conductor cross-section limits continuous current to low-signal or modest-power levels, so high-current automotive loads are outside the safe operating area. The 3.3 ft fixed length cannot be extended without adding resistance and potential failure points.

Questions about this item

Will the 4 mm banana plugs fit my multimeter jacks?

The male banana plugs measure 4 mm in diameter, matching the standard size used on most multimeters and power supplies.

How do I connect the alligator clips without a loose grip?

Open each clip up to 6 mm, seat the jaw squarely on the conductor, then release so the teeth bite cleanly — do not just hook the tip.

When should I replace these test leads?

Replace the pair if the insulation boots crack, the wire strands fray near the plugs, or the clip springs lose tension and slip off.
