Lockable T-Nuts are a practical upgrade if you assemble and disassemble your foil often, or if you simply want to keep your mast position consistent without wasting time re-aligning hardware in the tracks every session.

Once you’ve found your preferred position in the twin tracks, each T-nut can be secured with a small orange locking screw. This means:

• the T-nuts stay exactly where you left them, even when the mast/plate is removed
• you can return to the same mast position every time for consistent balance and feel
• you’re far less likely to lose T-nuts during setup, packing, or transport

Installation requires only one tool (Torx key).
