Obtained front and back shelf trim from Appliancepartspros, snapped front and back trim on to metal portion of shelf. Then slid glass shelf into front trim, metal shelf holder supports the glass. You definitely have to slide the glass into the front trim so it will hold, otherwise it’ll slip around. Won’t be secure and can’t put in fridge. Back trim helps keep glass shelf in place after it’s secured in the front. Put shelf into fridge. I’m not good at fixing a thing, but this was manageable.
