Fluke 4691-0 Test Lead Adapter Banana Plug

Product Description

The FLUKE 4691-0 is a banana plug adapter designed for use with connecting test leads in electrical test and measurement applications. This accessory extends or adapts the standard banana plug interface found on most handheld multimeters, clamp meters, and similar instruments. Finished in black, it is intended for the negative or common lead position in typical two-lead setups. Licensed electricians, HVAC technicians, and instrumentation techs use this type of adapter to maintain secure, low-resistance connections during voltage, current, and continuity measurements.

This adapter fits into workflows where existing test leads need to interface with alternative probe tips, alligator clips, or other banana plug accessories. It is suited for bench work, field service, and panel troubleshooting where a reliable plug-to-plug or plug-to-accessory transition is required. The compact form factor makes it easy to carry as part of a standard test equipment kit.

Key Features

• Banana plug interface compatible with standard 4 mm test lead connectors
• Black color coding for common or negative lead identification
• Compact adapter form factor for easy integration into existing test lead sets
• Sold as a single unit for individual replacement or kit supplementing

Compatibility

Designed for use with banana plug connecting test leads. Compatible with test instruments using standard 4 mm banana plug inputs, which is typical of most handheld multimeters and clamp meters that accept industry-standard test leads.

Installation Notes

This adapter is installed and removed by hand — no tools are required. Always disconnect test leads from any live circuit or energized equipment before changing adapters or probe tips. Inspect the adapter for physical damage or corrosion before each use. Follow applicable NFPA 70E safe work practices when using test equipment on energized electrical systems.
