So we’ve dedicated considerable Resources to solving your sewing issues: full time technicians; in stock parts; repair and refurbishing services; and training for Class 7 operation and maintenance. If you are tired of machine breakdowns and lost production time, let us help! You're running heavier plies, longer lengths, and making more slings than ever before. The multi-purpose Singer 7 style machines from the early 1900s no longer meet today's demanding production needs.  That's why Service Thread, the #1 supplier of sewing thread to the sling industry, developed the Service Class 7. Technical Specifications include: - 1.5" presser foot lift (up to 6-ply sling sewing) - Reverse stitching - Style 41 under bobbin - Heavy-duty 6×3 needle or 1000H - 301 lockstitch (up to 3.5 stitches per inch) - One horsepower clutch motor standard - Limited warranty - Ships fully assembled, tested and ready to sew ## Reviews from our Customers: *“The machine arrived installed in the table and ready to sew.
