Product Information

The TUSA TC-303 Fin Strap is a black replacement strap sold individually (1 piece) and built to fit all open heel fins, making it a simple fix when an original strap wears out, stretches, or snaps.

Who it is for

This strap is for divers who use open heel fins, the style with an adjustable heel strap rather than a full foot pocket, and who need to replace a damaged, cracked, or missing strap instead of buying a new pair of fins. It is a practical pick for travel divers who want a spare on hand, dive shops and rental fleets maintaining gear, and instructors keeping loaner fins in working order.

Key details

  • Manufacturer part number TC-303.
  • Black color.
  • Sold as a single strap, 1 piece per package, not a matched pair.
  • Designed to fit all open heel fins.
  • Barcode 685193428536 for easy identification at checkout or in a parts bin.
