Rib stitching secures the fabric to the wing ribs. Superflite carries the cord and needles you need to do it properly.

Choose waxed linen rib lacing cord in two styles: flat cord (500-yard roll) for a lower-profile, less noticeable stitch, or round cord (600-yard roll) for a more traditional look. Our stainless steel rib stitching needles come in straight lengths from 4 to 20 inches, curved needles from 2 to 8 inches, and bent-tip needles in 4 and 12 inches, so you can reach through any wing depth.

Before stitching, apply reinforcement tape over the ribs. The System 7 manual shows stitch spacing and knots in detail.
