Gemroom 12.5-inch Microwave Glass Plate | GE WB39X10003 & Maytag Turntable Replacement

Gemroom offers a practical 12.5-inch microwave glass plate designed to replace a worn or soiled turntable in select ovens. Crafted from durable borosilicate glass, this plate holds up to daily reheating and busy kitchen use while maintaining a clear, clean surface you can monitor as meals heat. It is sized to support standard 12.5-inch turntables, providing a stable base for everything from quick lunches to evening leftovers.
