Assemble units as described herein only. To do otherwise
may result in instability. All screws, nuts and bolts must be
tightened securely and must be checked periodically after
assembly. Failure to assemble properly, or to secure parts
may result in assembly failure and personal injury.

Back Attachment
1. Follow the space-planning layout
and stage the backs at their
location by size.
2. Starting at either end of a row,
loosely attach

” Torx head
screws to
1
⁄

-20 acorn nut through
the bottom rear hole in each of the
uprights (Figure 3).
3. Rotate the back assembly and
slide it between the uprights so
that the slot in the bottom of the
back bracket nests over the
loosely attached

head screws (Figure 4).
4. Rotate the back assembly until the
appropriate hole in the back
bracket lines up with the upper
rear hole in the upright. Place a

hole in the top of the back bracket
on the end-of-row upright and
attach to an
1

-20 acorn nut. Wait
to add the top screw on shared
uprights because the screw and
acorn nut are both shared
(Figure 4).
5. Repeat the same process until all
the backs are installed in the row
(Figure 5).
Note:
The bottom screws in the
uprights may be loosely attached
in the entire row to ease assembly.
The

and

should be tightened to engage the
locking feature in the acorn nut.
Refer to the space plan to
determine which top hole should
be used on the back bracket,
which determines the back angle.
The middle hole may be used if it
is not expressly noted.
6. Bariatric backs install the same
as standard backs, onto bariatric
uprights, which include factory
installed bariatric support brackets
(Figure 6).
