E-Stim Systems - 2B Bumpers - Powerbox Protective Case

The E-Stim Systems 2B Bumpers literally give your precious 2B powerbox a little more grip. This set consists of two semi-flexible protective pieces that click into place on the left and right sides of the 2B. They improve grip, help protect the casing from minor bumps and accidental drops, and offer a practical clip for carrying the powerbox. Available in black, red, blue, green, and yellow, so even protection doesn’t have to be colorless.
E-Stim Systems developed the Bumpers specifically for situations where a slippery powerbox and slippery fingers aren’t exactly a dream combination. The 3D-printed TPU is semi-flexible and gives the sides of the 2B extra grip. A small accessory for a pretty advanced power box—a bit like a good bumper on a sports car: hopefully never really needed, but you’re glad it’s there.

Specially made for the E-Stim Systems 2B

The Bumpers are specifically designed to fit the housing of the E-Stim Systems 2B Power Box. You’ll receive two separate pieces that attach to the left and right sides of the power box.
On the inside, they’re marked with L and R. This lets you see right away which part is for the left side and which is for the right. According to E-Stim Systems, this orientation is especially important if you want to use the built-in clip feature.
The bumpers snap into place on either side of the 2B. Small tabs fit into the screw holes of the housing, helping to keep the protective parts in place.

Better grip when fingers get slippery

The E-Stim Systems 2B is a serious powerbox, but its relatively smooth casing can be harder to hold onto during use. E-Stim Systems specifically mentions situations where latex gloves are worn or fingers have become slippery.
The semi-flexible TPU of the Bumpers adds a surface on both sides that’s easier to grip. As a result, the 2B sits more securely in your hand without having to put the entire powerbox inside a closed protective case.
The controls remain fully accessible. The Bumpers are located exclusively along the sides, making them more like protective side rails than a conventional case.

Extra protection for your 2B

In addition to providing more grip, the Bumpers serve a second purpose: they offer the 2B some protection if the powerbox is accidentally bumped or slips out of your hands.
The TPU can absorb part of a light impact before it hits the housing directly. Especially with a high-quality powerbox like the 2B, a little extra protection is certainly a good idea.
That doesn’t mean the Bumpers make your 2B indestructible. E-Stim Systems itself emphasizes that the semi-flexible TPU is durable but can break if bent to an extreme degree. So think of the set as an extra layer of protection, not as an invitation to test how well your 2B can bounce.

With built-in clip feature

The Bumpers aren’t designed solely to stay attached to the powerbox. They also feature a clip that makes it easier to attach the 2B to compatible gear.
If you want to use this feature, the L/R orientation is important. Position both Bumpers so that the openings of the clips face the same direction.
This makes the set useful when you want to move around during a session while still keeping the powerbox close to you. The 2B doesn’t have to stay in your hand the whole time, nor does it have to lie loose among cables and other equipment.

Easy to click onto the 2B

No complicated tools are needed for installation. First, check the markings on the inside and determine which part belongs on the left and which on the right.
Then click each Bumper onto the corresponding side of the 2B. The small raised areas on the inside fit into the screw holes on the powerbox and ensure proper positioning.
If you want to remove the Bumpers, E-Stim Systems recommends firmly grasping one Bumper and twisting it outward from the front. It’s simple enough that you don’t need a twelve-page manual—which is nice for an accessory that’s specifically designed to make life easier.

3D-Printed from Biocompatible TPU

E-Stim Systems manufactures the 2B Bumpers using 3D printing technology. According to the manufacturer, the TPU used is biocompatible and suitable for prolonged skin contact.
TPU combines flexibility with strength. It can flex slightly, offering a different level of grip and shock absorption than a hard plastic part.
Due to the 3D printing process, small layer lines may be visible. According to E-Stim Systems, this is normal and does not affect performance. It’s simply part of how each component is built up layer by layer.

Black – Discreet and Technical

The black 2B Bumpers keep the look of your powerbox understated and professional. Black pairs easily with dark gear and allows the protective parts to blend in visually with the rest of the equipment. The choice for anyone who thinks the 2B speaks for itself.

Red – A Powerful Accent

With red Bumpers, the 2B immediately gains more contrast. The color stands out clearly against the dark casing and makes your powerbox instantly recognizable among other equipment. Technology with a subtle hint of warning.

Blue – Cool and Recognizable

The blue version gives the 2B a modern pop of color without being overly flashy. A great choice when black feels too predictable and red is just a bit too bold.

Green – just a little different

With green Bumpers, you give the 2B a more distinctive look of its own. Green also makes the powerbox easily recognizable when you’re using multiple devices, cable sets, and accessories.

Yellow – impossible to miss

The yellow Bumpers are the boldest choice. They stand out clearly against the 2B’s dark casing, making them practical when you need to quickly locate your powerbox among other black devices. Anyone who chooses yellow has clearly decided that camouflage isn’t a priority today.

Five colors, same protection

All five color variants are technically identical. Black, red, blue, green, and yellow share the same construction, the same TPU, and the same fit for the E-Stim Systems 2B.
The choice of color is therefore entirely personal. You can match it to your outfit and other gear, create a striking contrast, or use color-coding to distinguish between different devices.

Cleaning and Maintenance

E-Stim Systems recommends cleaning the 2B Bumpers with hot but not boiling soapy water or a suitable medical-grade cleaning solution. Medical-grade cleaning wipes can also be practical.
Do not use corrosive cleaning agents or solvents. Furthermore, the TPU is not suitable for boiling, steam sterilization, or autoclaving.
Allow both Bumpers to dry completely after cleaning before reattaching or storing them.
Check them regularly for damage. The material is semi-flexible but not indestructible; extreme bending can damage the 3D-printed TPU.
