Product review (5 stars): Quality Construction
This rack fits perfect in the oven.  It slides out nicely and does not stick.  I have a gas oven with 2 racks and needed a 3rd rack for very bottom shelf, up off the floor of the oven itself.  I keep a pizza stone on the bottom rack to moderate heat supply while baking.  To match these racks, bake your cookies with Nordic Ware Natural Aluminum Commercial Baker's Big Sheet.  Pan exterior dimensions 21 x 15 x 1 inches and interior dimensions 19.5 x 13.63 x 1 inches.  They fit on these racks perfect with room around the whole pan/rack for airflow.  Having 3 racks in the oven allows me to keep the pizza stone in while baking 2 of these big baker's sheets at once (tho do rotate mid-way on your timer.)
