# Vac-U-Lock® Compatible Quick Connect Doubler Plug

Double the action with one machine. The Vac-U-Lock® Compatible Quick Connect Doubler Plug lets you mount two Vac-U-Lock compatible dildos side by side on your quick-connect sex machine for simultaneous double penetration, all in a single thrusting motion.

**How it works:** Slide each dildo's Vac-U-Lock socket onto one of the ribbed plugs. To adjust the spacing, loosen the screws with the included hex key, slide the plugs into position and tighten. The chrome quick-connect pin snaps straight into your machine's coupling. Push to lock, pull the collar to release. That's it.

Built from anodized aluminum alloy, it stays rigid and steady under fast, powerful strokes. The ribbed plugs grip each dildo securely, so both move together in perfect sync from start to finish.

Pair it with two Vac-U-Lock compatible RealCock dildos for a setup that feels intense, balanced and incredibly real.

**Key Features:**

-   Dual Vac-U-Lock® plugs: run two dildos at once for double penetration
-   Adjustable spacing: 2-1/2" default gap, customizable to fit your body
-   Tool-free quick connect: snaps into your sex machine in seconds and releases just as fast
-   Anodized aluminum build: 4-1/2" wide, strong, rigid and rust-resistant
-   Fits sex machines with a standard quick-connect (KlicLok-style) coupling

_Note: Dildos and sex machine are not included. Hex key included._
