Large Wireform on Tensioner Post

Replaces the standard tensioner post which has a 1/4" dia. wireform. Good for art yarn, ribbon yarn, or any yarn that is unusually large/thick


Here is a picture of the new Clamp Ring Assy

Tensioner Post Wireform sizes

Current and prior production used a 1/4" orifice (which is actually in the above picture). We will increase the standard size from 1/4" to 5/16" in August 2014. NKK belives that a minor increase in diameter to 5/16 will help to serve more users. This change increases the square opening by 50%.

Note: on the one hand, a larger 1" dia. opening seems like a good idea, but we should warn the user that there is a greater opportunity for the yarn to "move around" in the larger opening on its way to the spindle. This can cause yarn movement at the ball. The smaller opening does a more effective job in controlling the yarn. NKK recommends that unless you have a real need to wind really thck yarns, you are better off with the smaller wireform.
