Two ElectroRings are fun. Three can be even more interesting. Four? E-Stim Systems has already taken that into account. The
E-Stim Systems ElectroRing System Stacker is a clever insulating extension block that lets you add an extra ElectroRing to an existing ElectroRing System. Each Stacker creates space for one additional ring, keeps the individual metal rings electrically isolated from one another, and ensures a spacing of approximately 20 mm between them.
This transforms the original two-ring system into a modular structure that you can expand further. One Stacker for the third ring, another Stacker for the fourth, and so on. The electrical contact zones remain separate, giving you more options for positioning your e-stim contacts. It’s like Meccano for electroplay, except the building blocks here are metal cock rings with 4 mm connectors.
What does the ElectroRing System Stacker do?
The standard ElectroRing System consists of two separate ElectroRings connected to each other by an insulating spacer block. This keeps the metal rings electrically isolated from each other and allows them to function together as two separate contact points.
The
ElectroRing System Stacker builds on that principle. It is added to the existing system and allows for the installation of an additional ElectroRing without it coming into direct electrical contact with the preceding ring.
Each additional ring thus forms a separate potential contact zone within your setup.
20 mm spacing between the ElectroRings
The Stacker positions successive ElectroRings approximately
20 mm apart. This gives each metal ring its own place along the structure.
It is precisely this separation that is electrically important. If two conductive metal rings were to make direct contact with each other, they would no longer function as two independent contact zones. The Stacker prevents this by acting as an insulating bridge between the rings.
This allows you to position multiple metal contact points in sequence without them electrically becoming one large “ring family” that operates as a single unit.
One Stacker per additional ElectroRing
The expansion logic is simple: for
each additional ElectroRing you want to add to the standard two-ring system, you need one Stacker. E-Stim Systems does not specify a fixed maximum number of rings for the Stacker configuration. In practice, size, fit, and stability naturally become factors as your assembly gets longer.
- 2 ElectroRings: standard ElectroRing System with spacer and mounting hardware
- 3 ElectroRings: standard system + 1 Stacker
- 4 ElectroRings: standard system + 2 Stackers
- 5 ElectroRings: standard system + 3 Stackers
The first two rings require the Accessory Pack
An important detail: the Stacker does not replace the basic structure of the ElectroRing System.
For the first two ElectroRings, you’ll still need the standard spacer block and mounting hardware from the
ElectroRing Accessory Pack. The Stacker only comes into play when you want to add a third ring to that base.
If you only have two separate ElectroRings plus one Stacker, you’ll be missing parts needed to assemble the base system according to the intended design.
Here’s how to assemble the Stacker
First, assemble the standard ElectroRing System using two compatible ElectroRings and the standard spacer block. When expanding the system, the Stacker is then used to connect an additional ElectroRing to the existing structure.
The Stacker has integrated ribbed knobs. During assembly, both sides are tightened alternately by a small amount. E-Stim recommends about half to one full turn at a time, then switching to the other side.
It’s important to tighten evenly. If you tighten one side much more than the other, the mechanism may jam. In that case, turn the knobs in the opposite direction to release the tension.
Stacker on ElectroRing, not Stacker on Stacker
Multiple Stackers can be used within the same assembly, but there is an important installation rule:
there must always be an ElectroRing between two Stackers.
You cannot, therefore, attach two Stacker blocks directly to each other simply to create extra length. The sequence is always ring – Stacker – ring – Stacker – ring.
The last, front ElectroRing is secured with the standard mounting screws from the ElectroRing Accessory Pack.
Note the longer Stacker screws
A small technical detail deserves special attention if you own both an Accessory Pack and a Stacker. The ribbed mounting screws in the Stacker are
longer than the standard screws from the ElectroRing Accessory Pack.
Therefore, keep these parts separate during disassembly and cleaning. The standard mounting screws from the Accessory Pack are not suitable as replacements for the longer Stacker screws.
A difference of just a few millimeters may seem harmless until everything is laid out on the table again and every screw suddenly claims to belong to every part.
More contact points, more configuration options
The appeal of multiple ElectroRings lies not only in their physical construction. Each metal ElectroRing can form a separate electrical contact zone.
With a standard ElectroRing System, you have two such zones. By adding extra rings with Stackers, you create more separate points where you can make appropriate e-stim connections.
How you combine these contact points electrically depends on your power box, cables, and chosen configuration. Not every ring present needs to be connected at the same time.
The ElectroRings remain electrically isolated
The Stacker’s most important function is maintaining
electrical isolation between the individual ElectroRings.
This is what distinguishes simply placing multiple pieces of metal next to each other from actually creating distinct electrical contact zones. Each ring retains its own 4 mm connection points.
In a standard two-ring configuration, one plug goes to one ElectroRing and the other plug to the second ring. In more complex configurations, the additional separate contact points can be combined differently depending on the equipment used.
Part of the Modular ElectroRing System
The Stacker is part of the broader
E-Stim Systems ElectroRing platform. This allows you to combine ElectroRings with various inner diameters ranging from 25 to 65 mm with spacers, Stackers, and other system components.
As a result, the system does not have to remain in the same fixed configuration. You can adjust ring sizes, add additional contact points, and later revert the assembly to a simpler configuration.
If you want to use significantly more rings, you can also consider the separate E-Stim Ring Rack. That system is specifically designed to position up to eight ElectroRings as separate contact points.
Do Not Force
A setup with multiple ElectroRings and Stackers can become somewhat flexible. E-Stim Systems therefore warns against applying abnormal mechanical pressure to the Stacker blocks.
Do not force the assembly and do not use the Stacker as a load-bearing component. It is designed to hold ElectroRings in place and keep them electrically isolated, not to withstand significant tensile forces.
Dismountable for Cleaning
The Stacker can be disassembled for cleaning. First, remove it completely from the ElectroRing System.
The assembly contains three Phillips-head screws. After removing them, the top and bottom sections can be separated, and the ribbed mounting screws can be removed from the mechanism.
Store the small parts carefully during cleaning. Be especially careful not to mix up the longer Stacker screws with the shorter mounting screws from the standard Accessory Pack.
Allow all parts to dry completely before reassembling the Stacker and using it again in the ElectroRing System.
What else do you need?
The ElectroRing System Stacker is an
expansion accessory. Therefore, you will not automatically receive the ElectroRings, the base spacer block, the power box, and the connection cables that may be needed for a complete setup.
To build a three-ring system from scratch, you’ll need at least three compatible ElectroRings, the parts for the original two-ring configuration, and one Stacker.
If you already have a complete ElectroRing System, it’s simpler: add one extra ElectroRing plus one Stacker for each new position you want to create.

FAQ
What does the E-Stim Systems ElectroRing System Stacker do?The Stacker allows you to add an extra ElectroRing to an existing ElectroRing System. It positions the rings approximately 20 mm apart and keeps the individual metal ElectroRings electrically isolated.
How many E-Stim Systems ElectroRing System Stackers do I need?For every ElectroRing you want to add after the first two rings, you’ll need one Stacker. So for three rings, you’ll use one Stacker; for four rings, two Stackers; and for five rings, three.
Do I also need the Accessory Pack in addition to the E-Stim Systems ElectroRing System Stacker?Yes, if you’re building the system from individual parts. The first two ElectroRings are connected using the standard spacer block and mounting hardware from the ElectroRing Accessory Pack. The Stacker is used for each subsequent ring.
Can I attach multiple E-Stim Systems ElectroRing System Stackers directly to each other?No. An ElectroRing must always be placed between two Stackers. The assembly therefore proceeds as follows: ring, Stacker, ring, possibly followed by another Stacker, and then another ring. The last ElectroRing is secured with the standard mounting screws.
With the
E-Stim Systems ElectroRing System Stacker, your ElectroRing setup doesn’t have to stop at two rings. Add an extra ring per Stacker, maintain electrical isolation, and expand the system step by step. We’ll carefully package your expansion and ship it quickly and completely discreetly.
