The Klein Modbox Mounting Plate provides a durable and versatile mounting solution for vehicles, trailers, work trucks, and garage organization. Made in the USA from 1/8″ laser-cut steel, these plates are built tough to withstand heavy use and off-road conditions.
The mounting feet provide easy bolt-on installation to walls, workbenches, trailers, or flatbeds.
For custom setups, you can check out our fabrication parts—perfect for creating a custom Modbox mounting location. These mounting plates are available in raw steel (for easy painting or welding for a permanent solution) or black powder coat (ready to bolt in right out of the box).
