in Fig. 2-4A right illustration.
b. If the front flanges of the stationary sections are to
be mounted in front of the front rails (rails are tapped for
10-32 screws), mount the stationary sections as shown
in Fig. 2-4B right illustration. To provide increased bear-
ing surface for the screw head to securely fasten the
front flange to the rail, a flat washer (not supplied) may
be added under the screw head. However, if this mount-
ing method is used, the front panel will not fit flush
against the front rail because of the stationary section
and washer thickness. If a flush fit is preferred, method
2a should be used.
To adjust the slide-out tracks for smooth sliding action,
loosen the screws used to join the stationary sections to the
rails of the rack. Center the instrument, allowing the slide-
out tracks to seek the proper width, then tighten the
screws.
To secure the instrument front-panel to the rack, the rack
must either have universal hole spacing, or a hole must be
drilled and tapped for a 10-32 screw, see Fig. 2-5. Using the
hardware (not furnished) indicated in Fig. 2-5, secure the
5441 to the front rails of the rack.
3. Mount the stationary slide-out sections to the rear
rack rails using either of these methods.

Make sure that the stationary sections are horizontally
aligned so they are level and parallel with each other.
