This spool cap is designed to be used with spools/cones that have a larger center hole than the standard spool pin. It helps keep the spool/cone in place while allowing a smooth flow of thread for the machine.
Use this spool cap if a spool of thread whose core is 1/2 inch (12mm) in diameter and 3 inches (75mm) high is used on the spool pin.
