Product review (4 stars): GLRT182SAW2 Electrolux fridge. AKA "Frigidaire Gallery" replacement glass basic option
It's a rectangle of safety glass that fits my GLRT182SAW2 Electrolux fridge. AKA "Frigidaire Gallery"
It has no frosted markings or skid resistance surface, and like the piece it replaced, you must be careful when cleaning it or the temp change will cause it to shatter into a million bits. ..this is my second replacement.

This is the most reasonably priced replacement glass available online, and the shipping was fast with solidly protective packaging.
I will no longer pay for the fancier frosted glass. It doesn't make it any sturdier.

Most helpful info was another reviewer, Hector Gonzales, stating the exact size of  23.83 x 15.5in.

Do not use warm liquid products or water to clean this tempered glass.
Do not remove for cleaning without having first turned off the fridge and let the glass slowly acclimate to room temp on its own.
Glass will shatter and be one heck of a hazardous mess for pets, children and you if you do not handle the tempered glass properly.

ProTip: add some clear contact paper/laminate to both sides before installing. It will make it less messy if it does ever shatter.
