Wire Plate Rack
These wire racks just keep getting better and better. They're made of welded stainless steel and can be used wet or dry. They are impervious to solvents and other harsh chemicals which makes them easy to clean, especially if you're using them for drying varnished plates!
Whole plate and 8x10 racks hold 10 plates each, while the smaller formats are dual units that hold 20 plates each. Although they are not designed to be adjustable, the wire frame can be bent slightly by hand to accommodate unusual or in-between plate sizes.
The racks work equally well with glass or tin. Each plate is held at four points, so you'll have no worries regarding stability. And better yet, they can be stacked vertically to conserve bench space while drying or holding.
