Our keyboards arrive with rubber shims already installed on the hinges. Some keyboards have an extra set of shims in the box for other tablet models with different thicknesses.
If rubber shims are removed from the keyboard, they can lose their adhesive quality, and replacement shims are likely needed.
The Brydge 9.7 arrives ready to fit the iPad Air 2 or iPad Pro 9.7. For the iPad Air 1, iPad 5th Gen (2017), and iPad 6th Gen (2018), the shims will simply need to be swapped out with the extra set that came with your keyboard.
The Brydge 12.3 arrives ready to fit the Surface Pro 6th Gen, Surface Pro 5th Gen (2017) and Surface Pro 4. For the Surface Pro 3, the shims will need to be swapped out with the extra set of shims that came with your keyboard. If your keyboard did not come with them, please contact our support team to help with replacements.
