The Graphite Modular 5x4 9U Electronics Insert Pack is a practical way to separate and store small electronic parts while staying inside the broader Gridfinity-compatible storage system. It is suited to components, connectors, sensors, and bench supplies that are easier to work with when clearly divided. Product imagery currently reuses the 6U insert visuals as a representative reference, but this product is sized for the 5x4 9U format.
