This is for 1 clear glass convex replacement for a 12 inch thermometer sign.   The glass measures 12 inches in diameter, and can replace your broken or missing convex glass front face.  This will work on most round 12 inch diameter thermometers out there.  Measure your item before purchasing.  Some typical 12 inches thermometers are pictured in the first photo.   The glass is still wrapped in paper and was never used. We have several of these available.  If you collect soda pop, gas and oil, beer, and more, and need a replacement glass, this should be what you need.
