Ultra Sponge Bar (Needle Retainer) Strip for Plastic Knitting Machines. Fits Plastic BROTHER, SINGER, STUDIO, SILVER REED, KNITKING, KNITMASTER, & EMPISAL KNITTING MACHINES. Designed by a Calvin Klein Knitwear designer and Parsons School of Design graduate, the Ultra sponge bar is the ultimate knitting machine sponge bar. 1. Made from the perfect density of sponge - Medium Density. (The Science: High Density is too hard causing needles to get stuck, Low Density is not resilient and compresses too easily, Medium Density is soft enough to work with the needles, but strong enough to last a long time) 2. Smooth grey interlock mesh fabric sandwiches the foam on both sides for easy needle gliding. 3. Made to last. Will last 3-5 years with normal use (unlike most sponge bars which only last 1 year). 4. Easy to install instructions.
