UTC Vinyl Round Rib - Small

UTC Vinyl Round Rib - Small is a spooled fly-tying material made primarily for clear segmentation. Its round profile forms raised, regular ribs across the body, giving nymphs and pupae a structured outline. It can also be used for nymph wing cases, scud shellbacks and segmented abdomens where a defined ribbed surface is required.

Construction and use

Secure the material at the rear of the hook and wind it forward in even turns. The Small size suits smaller and medium-sized patterns when the body needs visible segmentation without an oversized rib. Because the material has a round profile, controlling the angle of each turn helps the ribs sit cleanly and remain evenly spaced.

• Profile: round ribbing material identified as Vinyl Round Rib.
• Uses: segmentation on nymphs and pupae, scud shellbacks and nymph wing cases.
• Patterns: flies requiring a clearly divided, orderly abdomen.
• Handling tip: keep consistent spacing and avoid crossing the material as you wind.
