This auxiliary spool pin from Brother accommodates dual-thread applications, enabling simultaneous needle work with enhanced thread management. The vertical orientation reduces tension and improves thread flow compared to the standard horizontal setup. Simply insert into the designated hole on your machine's upper surface — no tools required. Ideal for twin needle projects or as a replacement should your primary pin sustain damage. Compatible with Brother models; verify compatibility with your machine's documentation before purchase. Part number XG3488001.
