Fiji Cube overflow install question

[Gwcreefer]

The overflow bulkheads come with 2 gaskets, do you place 2nd between tank and overflow or does the 2nd go inside overflow and nothing between between tank and overflow? Thanks

Normally one’s installed on each side of the glass. So one sandwiched on the inside between the boxes and one against the external side of the glass before you slip the external box over the bulkheads to secure everything with the nuts.
