Klein Tools 69381 Heavy-Duty Alligator Clip Test Leads, 3-Foot

Yes. The 69381 leads terminate in standard banana-type plugs, which fit most multimeters and clamp meters regardless of brand, not just Klein meters. Klein lists them for use with Klein meters or any brand of multimeter or clamp meter that takes test leads. If your meter has recessed shrouded banana jacks, check the jack depth against your existing leads before ordering.

CAT III 1000V and CAT IV 600V. That covers distribution-level work inside a building and utility service entrance work at 600V, which is where most commercial electricians and facility MRO techs are taking readings.

Each lead is 3 feet (0.91 m) of 18 AWG double insulated wire. That is enough to clip a conductor in a panel and hold the meter at arm's length, but it is short for long runs, so for megger work across a distance you may want to reposition the meter rather than stretch the leads.

The plugs are 90-degree angled. A right-angle entry keeps the leads hanging down along the meter body instead of sticking straight out, so the meter sits flatter on a panel or in a hanging strap and there is less leverage pulling a plug out of the jack. If your meter's jacks are set close together or recessed in a well, straight plugs may seat easier.

Yes, that is what Klein points these at. The heavy-duty alligator clips bite onto wire ends and other conductors so you can leave them attached hands-free while the test runs, which is the usual requirement for insulation resistance testing.

One pair, so two leads, each with a banana plug on one end and a heavy-duty alligator clip on the other. That is a complete two-lead set for a single meter, not a single replacement lead.

The clip end measures about 1 inch high and 0.25 inch wide, so it is a compact heavy-duty clip rather than a large battery-type jaw. It will land on a lug, a terminal screw, or a stripped conductor end, but plan on a bare conductor to bite; these are not piercing or insulation-displacement clips.

Clips are nickel-plated iron, the plugs are copper, and the housing is PVC. Copper plugs keep contact resistance low at the meter jack, and the nickel plating on the clips resists corrosion on a truck or in a toolbag.

Klein Tools 69381. That is the manufacturer part number on the package for the 3-foot heavy-duty alligator clip test lead pair, rated CAT III 1000V / CAT IV 600V.
