These
bobbins share the common characteristic of having a round
core. There are a wide variety of flange styles represented.
Most of the flange styles are round and are listed with
one dimension under Flange Diameter. Square and rectangular
flanges show two dimensions under Flange Diameter. Those
bobbins that do not fit into the standard flange styles
are indicated as irregular. Please request samples or
a drawing to determine adaptability to your application.
