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. Custom designed modules can be provided at a reasonable cost for special applications.

We provide technical assistance for the selection and application of Dillblox power distribution systems, the design of Dillblox for new or different applications, the design of custom connectors and harness components, and the design and drafting of wire harnesses to be used with our Dillblox panels.

We also supply pre-assembled Dillblox Panels.  Whether you want a panel that is ready to wire and silk-screened, or one that’s loaded and electrically tested, we can get the job done.
