Klein Tools Discontinued Select ModBox Tool Boxes

Klein Tools appears to have discontinued select ModBox tool boxes, with no word as to why, or whether there will be any replacements or updated models.

So far, this move appears to have impacted all of their full-size tool boxes that feature a closing lid.

All of their original tool boxes now show the same message.

“This product is no longer in production.”

Milwaukee Tool’s patent infringement lawsuit against Klein Tools has progressed, with the legal complaint based on how Klein allegedly adapted patented Packout features.

Today – 12/15/25 – was set by the court as a deadline for both brands to report whether the United States International Trade Commission delivered final determination about the matter.

Maybe that has something to do with things.

Or maybe the costs were too high – these Klein ModBox products are manufactured in China and are likely subject to increased tariffs.

All we know is that several core Klein MoxBox products are now marked as being “no longer in production.”

At this time, it’s unclear if other Klein ModBox tool boxes and accessories, such as the drawered tool boxes, are impacted by whatever is happening with the original tool box models.

We asked Klein Tools’ marketing and media contacts why this is happening, but they have not yet provided any answers or insights.
