This keyguard comes with no attachment method. While gravity will hold the keyguard in place, most users prefer to stick it to the keyboard with tape or a mounting putty like Blu-Tack. There is room for a small amount of suction cup tape.
Size - The default size of the keyguard is the same as the keyboard. You may optionally choose to add an oversized flange which adds an additional rim around the perimeter, extending beyond the keyboard and containing optional holes which you can use to devise your own mounting method. These holes are 0.19" in diameter and fit a #10 machine screw. Our screw kits fit these holes.
Material - The default material is 3/16" clear acrylic. If you need a thinner keyguard, you can choose 1/8" acrylic styrene, but it makes for very shallow key openings. Alternatively, there are a number of 1/4' materials you can choose which leave deeper key openings and give you lots of choices for color. Personalize your keyguard with an unfinished wood for an old-world or executive look.
