Continuous Thread / Screw Top lids
Continuous thread lids or screw top lids differ from twist top lids which are sometimes called lug lids. The continuous thread locks onto the jar by screwing the lid down. Twist top lids have small "lugs" on the inside of the lid which locks onto the top of the jar.
The 2 lid types are not interchangeable.
The size of a continuous thread lid is measured across the inner diameter of the lid.
All our Bell jars take continuous thread lids.
