# 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
