Dr. Slick GBOB3 3-Inch Glass Bobbin Holder
A three-inch holder with two glass inserts, Delrin spool contacts and a shaped grip.

Description
Consider the short GBOB3 when your hand works close to the vise and you want a small-diameter glass thread path. Dr. Slick describes the glass range for extra-fine and synthetic tying threads. Use your own thread to check whether the narrow path feeds freely before committing to a pattern.

Fit and buying advice
Compare the four-inch ECO for more overall reach and brass spool contacts. Both are glass-insert options. Choose on handling and the size of the thread you use.
Questions about this tool
Is three inches the tube length?
It is the catalog size of the complete tool. Compare the tube projection separately if reach is critical.
What do the Delrin feet do?
They sit against the spool. The glass inserts are separate parts of the path through which the thread runs.
Will it feed large chenille?
The small glass path is intended for fine thread. Compare a model with a documented wider tube for bulkier materials.
