Rope clip

Using a 3/16 in (5 mm) security rope clip (sometimes referred to as a U-bolt), a steel security cable, and a padlock you can secure your computer to a desk, table, or other non-permanent fixture. For computers designed to accommodate the rope clip, knockouts at the rear of the chassis are provided.

To install a rope clip:

1.Remove the cover. See “Opening the cover” on page 12.

2.Use a tool, such as a screwdriver, to remove the two metal knockouts.

3.Insert the rope clip through the rear of the chassis and install the nuts using either an adjustable or an appropriate sized wrench.

4.Replace the cover.

5.Thread the security cable through the rope clip and around an object that is not part of or permanently attached to the building structure or foundation, and from which it cannot be removed; then fasten the cable together with a lock.
