Shockbox Capacitance Test Boxes

The Shockbox line of capacitance test boxes are designed with the small maintenance shop in mind. Our goal is to deliver high quality test boxes while keeping the costs low enough that the small aircraft maintenance shop can afford to perform test functions in-house, thus making themselves more profitable. Many small charter companies buy our test boxes to help eliminate lengthy down times and lower their maintenance costs.
