Vac-U-Lock System

The Vac-U-Lock system, designed by sex toy manufacturing giant, Doc Johnson, was the first interchangeable dildo system of its time, allowing the owner to swap out the dildo of their choice on their strap-on harness. With the innovative Vac-U-Lock system, there are no O-rings to hassle with, or the need to determine if a certain flared base will fit inside of the harness. Each Vac-U-Lock harness has a peg that comes out of the front side of the harness, that slides into any of the Vac-U-Lock dildo collection, providing a snug fit once in place.

The shopping experience is nearly effortless, as each of these strap-on harnesses are unisex, worn by women or men for hands-free strapon sex and utilizing any of the dildos designed to fit the specialized harness. Investing in a Vac-U-Lock set with your partner is an easy way to kick up the kink, or create quite the collection of cocks, ranging from average-sized to huge dildos and dongs. There are no limits when it comes to strap on sex with your partner and a Vac-U-Lock harness set!
