Tired of struggling with seatbelt buckles that lay flat or disappear into the seat? This minimalist, high-efficiency stabilizer is specifically designed for rear car seats where buckles tend to flop over, making it difficult for passengers—especially children—to buckle themselves in.
Universal Compatibility & Specs:
This model is designed to provide a Universal Fit for the vast majority of standard car seatbelt buckles.
- Internal Clearance: 50mm by 30mm, higher tolerance trough opening.
- Low-Profile Height: Only 50mm, ensuring a realistic look that doesn't stick out awkwardly.
Key Design Features:
- Front-Facing Opening: the opening ensures a more universal fit for thicker seatbelt buckles
- Minimalist Look: The slim 50mm height blends in perfectly with your car’s interior while still being strong enough to keep the buckle upright.
- Solid Construction: A clean, massive design with no unnecessary holes, resulting in a professional 3D-printed finish and maximum durability.
- End the Frustration: Keeps the buckle exactly where you need it, ending the constant "digging" between seat cushions.
