Keyguard for the Lenovo N22 Chromebook or the N23 Chromebook.  May fit other Chromebooks that share the same keyboard.  We've been told by a customer that it also fits a 2018 Acer Premium 15.6" Chromebook, but we don't know the model number.  Call for compatibility.

Keyguards for keyboards and laptops default to 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. 

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.)
