Quick answer
The Vac-U-Lock Deluxe Suction Cup Plug lets you mount any Vac-U-Lock compatible dildo to a smooth surface for hands-free use. Setup takes under a minute once you know the lever-release technique and surface requirements.
Why the surface matters
The suction cup relies on a smooth, non-porous surface to form a tight seal. Porous materials like wood or textured tile will not hold. Even on a perfect surface, a small speck of dust or soap residue can break the seal mid-session. Wipe the surface clean with a damp cloth and dry it completely before attaching the cup.
Vac-U-Lock compatibility
This suction cup works only with attachments that have the Vac-U-Lock base—a rectangular slot at the bottom. It does not fit standard O-ring harnesses or non-Vac-U-Lock dildos. If you own other Vac-U-Lock toys, you already have a compatible collection. If you are buying a dildo separately, confirm the listing says 'Vac-U-Lock compatible' before ordering.
Step-by-step setup
- Prepare the mounting surface: Choose a smooth, non-porous surface such as a glass shower wall, acrylic panel, tile (with no grout lines), or a polished countertop. Clean the area with a damp cloth to remove dust, soap scum, or oils. Dry it fully. A speck of dust is enough to break the seal—wipe the surface even if it looks clean.
- Attach the suction cup to the surface: Press the cup flat against the surface. Flip the lever on the side of the cup from the 'open' position to the 'locked' position. You should feel the cup pull tight and hear a slight pop as it seals. If the cup does not seal, the surface may be too porous or not perfectly flat. Try a different location before proceeding.
- Insert the Vac-U-Lock dildo: Line up the rectangular slot on the dildo base with the tab on the suction cup. Push the dildo onto the tab until it clicks into place. The connection is secure but not permanent—you can swap toys later. Do not force the dildo at an angle—it should slide on straight. Forcing it can damage the locking tab.
- Adjust the arm for your desired angle: The adjustable arm swivels and bends into position. Loosen the locking collar, move the arm to the angle you want, then tighten the collar to lock it. Test the position with a gentle push before using it with full force. The arm holds its angle firmly, but sudden hard thrusts can shift it. Re-tighten the collar if you notice movement.
- Test the hold before use: Give the dildo a firm tug to confirm the suction cup is secure and the arm is locked. If the cup lifts or the arm slips, repeat steps 2–4. A failed test now is better than a surprise detachment later. If the cup keeps slipping, try a different surface or a dab of water on the rim to improve the seal.
