This consists of a piece of Hammond 1455 series extrusion cut-to-length to hold any of the TADD-1, TADD-2, or TADD-3 full-size boards (not for the ‘mini’ units), plus a PCB panel to hold a powerpole pair in a back panel, and 8 case screw. There is a companion product, the type-specific end panels, that should be ordered with this case.
Note that this offering gives you the same thing that the original TADD case, formerly provided by the late and very missed TenTec sheet metal shop. In their day, they supported the early efforts of some of the major product still available today.
