Tool Aid's Long Back Probe Set, No. 23600, delivers precise, non-damaging access to harness connectors, fuel injectors, and sensors, even in tight spots. The kit includes straight, 45- and 90-degree stainless steel probes in .027" and .040" diameters, with 7"–8" lengths for hard-to-reach connections. A 2mm female connection fits most standard test leads, and the insulated body is rated up to 30v for safe testing. Available in three probe configurations and two colors for quick identification, the set also pairs seamlessly with Tool Aid's 21200 Clamp Probes.
