The Morton Circle & Border System is the ultimate accessory for the Morton Portable Glass Shop.
Putting a glass border around a glass circle uses a lot of glass and leaves you with hard to use scrap. The Circle & Border System changes how it's done. Create circles up to 13" (330 mm) and borders up to 14" (356 mm).
It comes complete with a computer program to calculate all the sizes, and video instruction to show you how to use your system.
