Carrier with vertical grid for supporting substrates in coater

A carrier for holding multiple substrates in a substantially vertical orientation while passing through a coater that provides a coating on at least a respective front face of each of the multiple substrates, each substrate having a back face disposed opposite the front face, the carrier comprising:

• a frame with an aperture having a horizontal dimension and a vertical dimension;
• a bottom tap bar affixed to the frame and extending horizontally along a bottom portion of the aperture;
• a top tap bar affixed to the frame and extending horizontally along a top portion of the aperture;
• a plurality of vertical support bars, each (i) having a length permitting engagement with both the top tap bar and the bottom tap bar while extending vertically across the aperture, and (ii) being positioned behind the back faces of the substrates;
• and
• a plurality of fasteners for fastening the substrates to the vertical support bars,
• wherein each vertical support bar has a plurality of fastener attachment positions for attaching to the fasteners at a plurality of vertical positions, and
• wherein the substrates can be stacked in the carrier in a way that permits substrates of different widths to be vertically stacked on top of one another in the aperture.
