Product review (5 stars): Great Replacement Grates
I'm thrilled!  These fit perfectly.  The range looks new again.  We have a Frigidaire GLGF376 DSF.  These are slightly different than the original, no curve and not quite as heavy, slightly darker gray, but a great replacement.  We had used Clear RTV silicone to level up the previous grates and keep them from moving around.  These do not need it!!  No more eggs sliding to the side of the pan.  The entire set cost less than ONE of the original grates.  Just a tip, if you place the grates in a garbage bag, pour in some ammonia, seal the bag, and let them sit over night, any residue will wash off easily.  We didn't know this for about a year and did some damage to the porcelain on the original grates with harsh cleaners and scrubbers.  I plan on using the ammonia process as soon as I notice any build up, I am confident these will hold up as well or better than the original grates.  These were exact measurement match.
