Lid Master Calipers - Large

Make one measurement and you have it's opposite immediately! It's an easy- to- use, accurate way to size lids for pots.

You can also make a lid for an already fired pot, by reassembling the wing nut and screw in the 12-1/2% hole. This way your lid will shrink to fit the pot.

Large Lid Master: Just like the regular Lid Master the Large Lid Master measures pots up to 20” wide!
