Thread Spool Caps
We recommend these Thread Spool Caps (TSC) as they act as a check valve to prevent puddling of limp threads and unruly unspooling of kinky threads. Threads are routed from the spool through the cap hole and then through the upper thread guide of the Color-Go-Round thread carousel, thus providing unparalleled smooth feeding of problem threads. Thread Spool Caps are available in packages of eight.
