Keyguard for the Dell P22T Chromebook 11 and other Chromebooks that use the same keyboard. Call if you are not sure if this will fit your model.
The default material is 3/16" clear acrylic. 1/8" high-impact PMMA is available for users who require the openings to be shallower, but is not recommended, since it is more flexible and may become warped or dislodged. There are also a number of 1/4" thick materials available.
No attachment method is provided with this keyguard. You'll need to attach it yourself with something like double-sided tape, Velcro, or mounting putty (Blu Tack, etc.)
