Stream Deck XL or MK2: Which Grizzly GT3 Button Box Fits?

Your existing Stream Deck determines which GT3 button box you need: Grizzly offers separate versions for the Elgato Stream Deck XL and Stream Deck MK2. Neither version includes the Stream Deck itself.

Check the model first, then choose your controls

Check the exact model name of your Stream Deck and choose the matching button box. The two product versions are designed for different Stream Deck models; do not assume they are interchangeable.

Next, review your existing setup: which functions are easy to reach on the steering wheel, which do you use through the Stream Deck, and where would rotary controls or extra switches help? If your current layout works well, an empty space on your rig alone is no reason to buy more hardware.

What the combination adds

The GT3 button box adds physical rotary controls and switches to your Stream Deck. The encoders have aluminium covers and the front plate is made of 3 mm carbon. The main question is whether these extra controls would be useful in your own setup.

Plan which functions you want to assign to each control. The actual setup depends on your software and preferred mappings. A blanket promise of compatibility with every game or operating system would not be a reliable basis for choosing.

Installation and what is included

According to the product specifications, the matching Stream Deck slides in from the rear and is secured with screws from the front. The button box has a USB-C connection and a USB-C cable is included. Buy the Stream Deck separately or use the device you already own.

Fitting the Stream Deck and mounting the complete unit to your rig are two separate questions. If you are unsure about rig mounting or software setup, describe your setup through the contact page before buying. The exact Stream Deck version, your rig and your intended use are what matter.
