Large Spool Cap for Juki / Singer Domestic Machines for 100-9340 | #R12373210B

The spool cap does a straightforward but critical job: it seats over the spool pin and holds the thread spool in place during sewing, preventing it from tilting, spinning sideways, or running off the pin mid-seam. The smooth, rounded plastic rim lets thread unwind cleanly from the spool without snagging on the cap edge, which supports even tension and cleaner stitches throughout a project. Molded from shatter-resistant plastic, this large cap measures approximately 1-3/4 inches wide with a center hole of 0.22 inches, sized for standard domestic spool pins. This listing includes a 2-pack. Also sold under alternate numbers 38003700, 416500701, 4161571-01, 68003700, R12373209 and R12373210. Fits Singer and Juki machines -- 64 proven models.
