This accessory attaches to your seat belt's buckle tongue, so the one measurement that actually matters is how it lines up with your factory hardware.

The Measurement That Matters

The lock-tongue length on this accessory is 20-22mm, sized to fit a wide range of factory buckle tongues. Measure your existing buckle tongue width before ordering if you are unsure.

Brand Design vs. Fit

The brand-specific logo designs (BMW, Mercedes-Benz, Audi, Volkswagen, Toyota, Honda, Ford, and others) are a styling choice, not a fit difference - the lock-tongue dimension is what determines whether it physically fits your buckle, regardless of which logo you pick.

After Installing

Always confirm the belt still latches fully and securely at the buckle before driving.

Frequently Asked Questions

Does the car-brand design affect the fit?

No - the logo design is cosmetic. Fit is determined by the 20-22mm lock-tongue length, which is the same across all brand designs.

What if my buckle tongue is a different size?

If your factory buckle tongue falls outside the 20-22mm range, this accessory may not seat properly - check your own buckle tongue width before ordering.

How do I know it is installed correctly?

The belt should still click into the buckle fully and securely, with no looseness or resistance compared to before you attached the accessory.
