▼ Attach Bolt-On Slide-Rail Assemblies
To attach bolt-on slide-rail assemblies to the rack:
1. Position a slide-rail assembly in your rack so that the brackets at each end of
the slide-rail assembly are on the outside of the front and rear rack posts (see
FIGURE 3-3).
2. Attach the slide-rail assembly to the rack posts, but do not tighten the screws
completely.
Choose one of the following methods to attach the slide-rails. The method you
use varies, depending on the type of rack:
■ If your rack has threaded mounting holes in the rack posts, first determine
whether the threads are metric or standard, then insert the correct mounting
screws through the slide-rail brackets and into the threaded holes.
■ If your rack does not have threaded mounting holes, insert the mounting
screws through both the slide-rail brackets and rack posts, then secure them
with the caged nuts.
