L-Type Thread Guide
This L-shaped thread guide routes upper thread around a fixed bend point, keeping tension steady as thread changes direction along its path.
Fits
- Jack F4, F5, F6 and JUKI single needle lockstitch machines
Why Replace It
A worn L-type guide develops rough edges right at the bend point, where thread friction is naturally highest — a common spot for fraying.
FAQ
Why do L-shaped guides wear faster than straight ones?
The bend point concentrates thread friction in one spot, so L-type guides tend to show wear sooner than straight thread guides.
