This is adapter for this terminal adapter.

Slide ESP in place cover.

Provides:

• clear access to terminals;
• ability to mount with screws;
• place for your own labels on sides;
• double sided usb access;
• basic protection from surprise shortcuts.

Mind that it was never made to be used as storage box, so cover sits good and surely not loose, but don`t throw anything at it.

Warning check your ESP width. I did not so if You will have to move on connectors line 2,54 mm outside, usb cable should still fit.
