If you’re a fan of virtual reality, you’ve probably heard of the Valve Index. This high-end headset offers an immersive experience like no other, but it also comes with a unique feature that some users may not be familiar with.

That is the slot in the front of the headset, which serves a very important purpose. In this article, we’ll explore what this slot is for and why it’s an essential part of the Valve Index.

What Is the Slot in the Valve Index For?

The slot in the Valve Index is officially known as the “Frunk” (short for front-trunk). It’s a small compartment located on the front of the headset that can be opened and closed using a button on top. The Frunk is designed to hold various accessories that can enhance your VR experience.

What Accessories Can You Use with the Frunk?

Valve has designed several accessories specifically for use with the Frunk, such as:

  • The Hand Strap: This strap allows you to attach one or both controllers to your hand for a more secure grip.
  • The Nose Rest: This small piece of plastic can be attached to the Frunk and helps reduce pressure on your nose while wearing the headset.
  • The Prescription Lens Adapters: If you wear glasses, these adapters allow you to use your prescription lenses instead of wearing glasses inside the headset.
  • The USB Extension Cable: This cable allows you to connect additional USB devices to your computer without having to take off your headset.

Of course, these are just a few examples of what you can do with the Frunk. There are many other accessories available from third-party manufacturers that can be used with this handy feature.

Why Is the Frunk Important?

The Valve Index is an incredibly advanced VR headset that offers some of the best visuals and controls on the market. However, it’s also a very expensive piece of equipment, and users want to get the most out of their investment. That’s where the Frunk comes in.

By providing a space for accessories, Valve has given users the ability to customize their experience in ways that would not be possible otherwise. Whether you need prescription lenses or just want a more secure grip on your controllers, the Frunk allows you to do it all without having to purchase an entirely new headset.


In conclusion, the slot in the Valve Index is an essential feature that sets this headset apart from its competitors. By providing a space for accessories like prescription lens adapters and hand straps, Valve has given users more control over their VR experience than ever before. So if you’re considering purchasing a Valve Index or already own one, be sure to take advantage of this handy feature and see what kind of customizations you can make!
