This is our modular fuse holder that we use to build our Pro Panels. Each module holds 4 ATO fuses. These modules can be locked together to build as big a fuse panel as you like. (see side picture)  Each module comes with enough terminals to make one fuse module.  A super slick way to build your own fuse panel! For Hotrods, Muscle Cars, Trucks, Tractors, anything you want to build!  Build it yourself the way we do.  Sold each.
