This keyguard fits the Solidtek ACU-595U Mini keyboard, also sold under the Adesso brand, and sometimes having different model numbers, including ACK-595UB, KB-595BU, KB-595BP, 595 PS2.
The default keyguard comes with no attachment method. It's up to you to mount the keyguard on the keyboard with something like Velcro or double-sided tape. However, you can optionally order it with Velcro or attached straps to hold it in place.
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.. Note: The function keys along the top row will be difficult for large fingers to reach if you go with a thicker acrylic.
