# Vac-U-Lock® Large Suction Cup Plug

The Vac-U-Lock Large Suction Cup Plug is the stable, no-fuss base that turns any smooth surface into a hands-free mount. Larger than the standard plug, it provides a wider suction footprint meaning more grip, more stability, and less movement during use.

Press it against any smooth flat surface tile, glass, hardwood, bathtub floor twist to lock, and it stays put. The large-diameter base distributes force evenly so the connection holds even at full intensity. Compatible with all RealCock Toys dildos and any Vac-U-Lock® attachment worldwide.

The standard choice when you need maximum stability over 360° swivel range of motion.

**Key Features:**

-   Large 4" diameter base: wider footprint for maximum stability
-   Strong suction lock: holds firm on tile, glass, and smooth flat surfaces
-   Compatible with all Vac-U-Lock® attachments including all RealCock dildos
-   Hands-free: no harness or mount required
-   Body-safe, easy to clean, travel-friendly
