321 3U to 1U Adapter

321 (three to one) is a Eurorack Modular adapter that is designed following the Intellijel 1U panel size. The adapter lets you install 3U modules (4HP max) horizontally on the 1U row of you case. You can install one 4HP module or two 2HP modules or one 1HP and one 3HP module. Since there is no threaded strip or slide nuts underneath to secure the M3 screws, it uses M3 hex nuts. The adapter is 26HP wide.

The panel is made of pcb with matte black solder mask. The exposed copper is coated using the ENIG-RoHS (Nickel and Gold) finish for extra durability and nice golden color.
