The Klein Tools Tradesman Pro Large Hard Case (Model 5189) is built for professional electricians and contractors who need reliable, on-the-go protection for their meters, tech devices, and precision tools. The hard outer shell shields contents from impacts when the case is stored inside a tool bag or pouch — keeping your multimeter, voltage tester, or small parts safe during transport between job sites. The full-zip closure keeps everything securely contained, making it equally useful for organising small parts, connectors, or accessories that tend to get lost in a larger bag. At just 0.6 lb and sized at 10.25″ × 5.5″ × 2.25″ (133 cu in), it’s compact enough to slip into any tool bag without taking up valuable space.
