the oven’s interior
Slightly raised edges or bent ends designed to rest on oven rails
A chrome or dark metal finish
If the rack fits inside the oven and sits securely on its supports, this is a strong possibility.
A Rack for a Warming Drawer or Other Appliance
Some kitchens have warming drawers, combination ovens, or other appliances that use removable racks. A rack that resembles an oven shelf may have belonged to one of these.
Check the kitchen for an appliance with matching dimensions, rails, or mounting points. Look for a manufacturer’s label or model number if you find a likely match.
A Large Cooling or Baking Rack
A large wire rack can also be used for cooling baked goods, draining
food, or holding trays. However, a rack designed for countertop use may have short feet rather than the shaped ends needed to
slide into an oven.
