Vac-U-Lock

What is Vac-U-Lock?

A universal mounting system featuring a standardized hole in the base of a toy that clicks securely onto compatible plugs, harnesses, machines, and other accessories.

How Does the System Work?

The Vac-U-Lock system uses a simple but effective mechanical interface. The toy has a round hole molded into its base, and the mounting accessory has a corresponding plug that inserts into this hole. The fit creates a friction lock reinforced by the natural grip of silicone on the plug surface. No screws, no adhesives, no complicated latches. The toy clicks on, stays firmly in place during vigorous use, and pops off cleanly when you twist and pull.

This standardized interface means a single toy can move between a harness, a suction-cup adapter, a machine mount, or a furniture attachment in seconds, dramatically expanding the versatility of every compatible piece in your collection.

Why Choose Vac-U-Lock for Fantasy Toys?

Many indie fantasy toy makers have adopted Vac-U-Lock compatibility as an option alongside or instead of the traditional suction cup base and flared base designs. The advantage is modularity. A collector with 10 Vac-U-Lock compatible toys needs only one harness, one machine adapter, and one wall mount to use every toy in every configuration. Without it, each toy is limited to whatever base type it was originally poured with. For custom orders, specifying a Vac-U-Lock base instead of a suction cup gives the buyer maximum future flexibility. The hole does not compromise the structural integrity of the base because it is molded during curing, not drilled after the fact.

What Are the Compatibility Considerations?

While the Vac-U-Lock name originates from a specific manufacturer, the plug diameter and depth have become a de facto industry standard that many makers follow. However, not all implementations are identical. Plug diameter, taper angle, and insertion depth can vary slightly between brands. Before purchasing accessories, confirm that your toy's base hole matches the plug dimensions. Most fantasy toy makers list compatibility specifications on their product pages. When in doubt, measure the hole diameter and depth with calipers. A snug fit is critical: too loose and the toy wobbles or detaches during use, too tight and removal becomes difficult.

What Mounting Options Are Available?

The ecosystem of Vac-U-Lock accessories is extensive. Harness plugs allow strap-on use with any compatible toy. Suction adapters add wall or floor mounting to toys that were not originally poured with suction cups. Machine adapters connect toys to reciprocating devices for hands-free automated use. Handle grips add an ergonomic wand-style handle for partner play. Each accessory accepts any Vac-U-Lock compatible toy, so upgrading your accessory collection amplifies the utility of every toy you own.
