Used in commercial embroidery machines to add space between needle bar and hook cover

Used in commercial embroidery machines to add space between needle bar and hook cover. Recommend using Nylon, or try polyfex this is a very thin build just .5mm scale Z as needed to add space. I consider this a temporary fix but should last for a while do not use in machine with plastic needle bar parts. You need to cut at center of each hole so to fit into needle bar.
