Product review (5 stars): Like having a new oven
We bought a house with a good (but used) stove in it, however the racks were pitted and rough.  Evidently, the previous owner had run the self-cleaning feature and left the racks in the oven (something you absolutely should not do).  Baking pans did not slide in and out easily, and neither did the racks.  These 4acks fit the oven perfectly -- it is like having a new oven!  Baking pans slide easily in and out.
