This Desktop Bottom Table Standoff is the perfect accessory piece to maximize protection of your workspace without taking up valuable space on your desk. It is made of a 5/8" diameter solid aluminum cylinder with a flat head that fits material between 0" - 5/16" thick and requires a 1/4" diameter hole. This standoff also has a 7/8" distance from the wall and a metric M6 thread, requiring a #8 screw (sold separately). Installation is easy - just unscrew the head, install the body under the desk, place the acrylic on top, and screw the head back on. This product is sold individually and comes with a clear anodized finish.
