Lid Master Large

Same as the regular Lid Master™ only larger! Measures pot up to 20" or 50.8 cm.

Make one measurement and you have its opposite immediately. The Lid Master™ does the work of two calipers with far greater speed and accuracy!

The secondary hole accommodates for 12.5% shrinkage factor and instantly shows how much a pot will shrink during firing. This allows for sizing finished work precisely or to make lids for already fired pots (no need for a conversion ruler).
