FOIL LOCK
Secures board and foil.
The first dedicated security system for foil boards. Patent pending.
Your foil setup is a high-value investment — but securing it can be a challenge.
We developed the Foil Lock to close this gap. It is a simple, tool-free system that locks your board and hydrofoil together in seconds — providing security and peace of mind for vanlife and camping trips, as well as beach days or lake sessions.
Whether you are wingfoiling, pumpfoiling or surf foiling, the Foil Lock is designed to work with all standard foil boards using the US-Box track system.
 
How it works
Insert into the track. Slide the Foil Lock into your US-Box track.
Cover the mast plate screws. The screws are covered, so the mast base plate cannot be removed.
Lock your setup. Secure your board and foil to a fixed object using our Looplock cable (or any compatible lock).
 
Technical Highlights
Dual-Lock Innovation (Patent Pending).
Secures both the board and the foil mast at the same time.
Premium Stainless Steel.
Made from high-strength marine-grade stainless steel for long-term use in saltwater environments.
Universal & Adjustable.
Designed to fit all standard US-Box foil tracks. The adjustable mechanism compensates for different track depths and mast base variations.
Tool-Free Setup.
Lock and unlock your setup in seconds — no tools required.
Compact & Travel Ready  
Lightweight and portable design (approx. 120 g without cable).
 
Compatibility & Fit
Designed to fit all standard US-Box foil tracks.
Compatible with all common foil systems within a mast plate length of up to 215 mm (e.g. Fanatic, Gong, Sabfoil, Duotone, RRD, Naish, F-One).
Exceptions – two specific setups are currently not compatible:
– Duotone Carbon Mast Slim 2.0 D/LAB (exceeds 215 mm length)  
– Carbon SLS tracks (e.g. Skybrid SLS, Sky Style SLS) due to increased track depth
 
If your mast plate is under 215 mm, the Foil Lock will fit. If in doubt, just measure along the track. Feel free to contact us.
 
 
Modular System
If you want to secure your board without the foil, you can use the Fin Lock US-Box. Thanks to the modular system, multiple boards can be secured using one Looplock cable.
