cringle

A cringle is a reinforced opening in fabric or similar material that provides a secure point for attaching lines, hooks, or fasteners. It typically comprises a hole surrounded by a fabric or leather welt and may incorporate a metal ring, grommet, or eyelet to strengthen the edge and prevent fraying. Cringles may be sewn directly into the material or formed by inserting a separate ring or grommet.

In nautical use, cringles are common on sails, tarpaulins, and similar textiles. They serve as attachment points for halyards, sheets, reefing lines, and tie-downs, and are often located at corners or along edges. The reinforcement helps distribute stress and reduces wear where the line repeatedly bears load. Reef cringles, for example, are placed at reef points to facilitate reducing sail area.

Beyond sailing, cringles appear on camping gear such as tents, tarps, and awnings to accommodate guy lines and stakes. They are also found in upholstery, drapery, and leather goods where cords or laces pass through fabric without tearing it. In some contexts, the term refers to the ring itself as well as the reinforced hole that accepts it.

Maintenance involves inspecting cringles for signs of wear, such as torn fabric, loose rings, or deformation of the surrounding welt. Damaged cringles should be repaired or replaced to preserve the strength and safety of the attachment point.
