This is a small Revere Ware Double Boiler Insert for 1 quart pan. Insert measures approx 2 1/4" deep x 6" outside diameter, 5 1/2" inside diameter. 

Make sure your pan is deeper than 2 3/8" for adequate water underneath. This is a heavy sturdy insert.

Nice pre owned condition. Normal wear with utensil marks. Still shiny.
