NEW in 2022: Tube Orifice Bars have 3D printed black tube with a delta opening that will keep your yarns centered while spinning.
Hook orifice bars come standard with spinning wheels and flyer heads. They are the part that snaps to the front of your flyer. 
Our hook orifice is by-passable, giving you full freedom to spin any weight of yarn, including super bulky or embellished art yarns, without getting trapped or snagged in your orifice.
