Vac-U-Lock is the interchangeable pleasure system built around the Vac-U-Plug, revolutionizing harness play and offering endless possibilities to mix and match within your collection to build the perfect toy.
Designed to address the issues most common to strap-on play, the Vac-U-Plug's unique snap-in assembly holds any attachment securely in place at a perfect 90 degree angle to the body with no slipping during even the most vigorous play. Vac-U-Lock harnesses also feature a cushioned front panel to ensure comfort.
In addition to harnesses, the Vac-U-Lock collection has grown to include a variety of accessories like special handles and items for fetish play, and much of Doc Johnson's inventory is now manufactured to be Vac-U-Lock compatible for unlimited pleasure potential.
