Depending on the complexity and the current production schedule, custom box lead times can vary between 10 days and 2 weeks after the receipt of the order, . Please note that there are some applications that we cannot accommodate due to geometry. Historically, there have been only a few of these situations.

    • A drawing with dimensions or images of the test piece will be required.

    • Custom boxes are not accepted for return, unless there is a failure due to workmanship quality. Unfortunately, we cannot always guarantee performance of the design. Many of these applications are first time events with no opportunity for testing.
