Stonfo Bobtec 2 Large-Tube Bobbin Holder
The Bobtec with a larger tube for thicker tying material, identified as Bobtec 2 on the retail bag.

Description
Choose the Bobtec 2 if the material you want to use is difficult to feed through the standard Bobtec 1. The larger tube is the deciding feature for that job. A sliding control still lets you set the resistance from the spool, so you can address feed and tension separately.

Fit and buying advice
If you are replacing a damaged fine-thread holder and your material already passes freely, compare the standard Bobtec 1 first. Both versions use a hardened-steel outlet bushing. Look at the material you feed most often before committing to the larger passage.
Questions about this tool
When should I switch from the standard tube?
Switch if your usual material binds or catches while you try to feed it through the standard holder. Compare tube fit with the material that actually causes the problem.
Will a thicker material always feed through?
Stonfo calls it a larger tube without stating a bore in the cited specification. Check unusual materials before relying on the fit.
Can I use it when switching spools between patterns?
Stonfo describes a quick spool change. Check the tension again when you switch materials so payout feels right for the new wrap.
