DillBlox Power Distribution Modules are designed to provide flexible, easy to configure electrical distribution panels using standard off the shelf components. DillBlox Modules have a unique interlocking edge and can be joined together using the dovetail wedge. The result is the creation of a strong, rigid panel assembly. Standard Modules are available to accept most plug-in devices that are widely used in over-the-road, off-road, construction, and agricultural vehicles.

Fargo Assembly of PA provides technical assistance for selection and application of Dillblox power distribution systems, design of Dillblox for new or different applications, design of custom connectors and harness components, and design and drafting of wire harnesses to be used with Dillblox panels.
