The F-One Lockable T-Nuts (x4) are engineered to make foil setup faster, easier, and more reliable, while ensuring stable and precise positioning.

Thanks to their integrated locking system, the nuts stay securely in place inside the twin tracks, preventing unwanted movement and making installation easier—even in challenging conditions.

This smart design helps you save time during setup and ensures your settings remain consistent throughout your session, improving both performance and safety.

It also prevents losing the T-nuts during assembly or handling, making them an essential spare or upgrade for any foil rider.

Compatible with most US box / twin track systems, they are made from corrosion-resistant materials for long-lasting use in marine environments.

The package includes screws and a positioning template to ensure perfect placement from the start.
