Member Master Large Giffin Grip Curved Pottery Tray

This product functions identically to the standard Lid Master but also allows you to properly measure this with larger pots with a maximum diameter of 50.8 cm Take one measurement and you have the opposite immediately. The Lid Master does the work of two calipers with much more speed and accuracy! Plus, you can turn the screw back into the bottom set of holes and it immediately shows you how much a pot will shrink during baking. So you can make your finished work exactly to size or make lids for already baked pots. With the 12 1/2% shrink ratio, you won’t need a conversion ruler.
