VAC U LOCK

One system, endless combinations. Vac-U-Lock is Doc Johnson's modular attachment system that lets you swap dildos between harnesses, sex machines, and suction cups without buying a new setup each time. A prong adaptor locks into the hole in the base of any compatible toy, creating a secure vacuum grip that holds firm even during vigorous use.

How It Works

  • The Adaptor — A plug or prong that connects to your harness, sex machine, or suction cup mount
  • The Toy — Any Vac-U-Lock compatible dildo with the standard hole in the base
  • Insert the prong into the toy's base hole — the vacuum creates a vice-like grip that stays put

Why Vac-U-Lock?

  • Versatile — One dildo works across harnesses, fucking machines, and suction cup mounts
  • Hands-free — Secure attachment frees your hands for everything else
  • Secure grip — Vacuum lock holds firm during vigorous play
  • Cost-effective — Build your collection of attachments without replacing the whole setup
