Orifice Bar

A wooden slingshot with a metal hook and elastic bands.

SpinOlution offers three interchangeable orifice bar styles to support a wide range of spinning preferences and yarn types. Every SpinOlution wheel comes standard with an open hook orifice bar, while optional tube orifice bars and delta orifice bars are available for spinners who want more control.

The hook orifice bar is fully by-passable, allowing complete freedom to spin anything from fine yarns to super bulky or heavily embellished art yarns without snagging or restriction.

Tube orifice bars feature a 3D-printed tube with a standard round orifice.

Delta orifice bars feature a 3D-printed tube with a delta-shaped opening that helps keep yarn centered while spinning, specifically engineered to center yarn for fine, precise spinning.

To ensure proper fit, measure your flyer shaft bar diameter which will be either 1/4” or 3/8” so your dealer can order the correct orifice bar for your wheel.
