SMUGDESK 2pcs 4mm Banana Plug to Alligator Clip Test Leads 1m Red Black

Test Lead Kit for Multimeters

This two-piece set supplies one red and one black test cable, each one metre long, for connecting a multimeter to a circuit. Standard 4 mm banana plugs fit most digital multimeters, power supplies and bench instruments. Sturdy alligator clips on the opposite end grip wires, terminals and component leads securely. The kit suits electricians, technicians and hobbyists performing routine voltage, continuity and fault-finding tasks.

4 mm Banana Plug Interface

The decisive specification is the 4 mm banana plug, which determines compatibility with your meter or power supply. This plug size is the de facto standard on the majority of general-purpose digital multimeters and bench equipment. If your instrument uses a different connector — such as 2 mm plugs, BNC or proprietary terminals — these leads will not mate without an adapter. Verify the input jack diameter before purchasing.

Insulation and Handling

Flexible insulated jackets protect the conductors during daily bench and field work, maintaining safe isolation while the cables are bent or routed around components. The alligator clips open wide enough for typical component leads and screw terminals, providing a firm mechanical hold that resists accidental disconnection during measurements. No active cooling or power draw is involved; the leads are passive accessories that add negligible resistance to the measurement path.
