teardrop-shaped hole pattern on each beam should be
facing upward (or away from you). (Fig. C)
2. Insert the free end of the diagonal beam into the free
end of the horizontal beam. Align the holes, and insert
both beams into the U-shaped bracket at the top of
the opposing vertical beam. Use the included hex
key or drill bit to thread the vertical assembly bolt
through the holes and into the weld nut attached to
the U-shaped bracket. Do not fully tighten the
bolt yet. (Fig. D)
3. Swing out the bottom horizontal beam, and insert
it into the U-shaped bracket at the bottom of the
opposing vertical beam. Thread a vertical assembly
bolt through the holes and into the weld nut. Do not
fully tighten the bolt. (Fig. D)
4. Repeat steps 1-3 to assemble the remaining upright
frame. Once all are assembled, fully tighten the bolts.
Be careful not to over-tighten the bolts; there should
be no deformation of the U-shaped brackets and/or
horizontal beams.

Crossbeam Installation (Fig. E, F, G)
nOTE: It is recommended for one person to hold the
upright frames in place while a second person installs
4
the crossbeams
.
1. There is a set of locking tabs at both ends of every
4
crossbeam
. To begin assembly, take one crossbeam
and insert the tabs into two of the holes on the lower
portion of one upright frame. Engage the locking tabs
into the holes using a downward motion. The locking
pin hole should be at the top. Make sure the end of the
crossbeam is flush against the upright frame. (Fig. E)
2. Repeat for the opposite side of the upright frame.
Tap the ends of the crossbeam closest to the upright
frames with a rubber mallet until fully seated. The
crossbeam and locking tabs should easily slip into
place. If they do not, then recheck the alignment of the
teardrop-shaped holes and tabs. Too much force may
damage the interlock between the crossbeam and
upright frame. (Fig. F)
3. Using the methods listed above, install another
crossbeam to the opposite side of the upright frames,
parallel to the first crossbeam you installed. Make sure
both crossbeams are at the same level.
4. Repeat steps 1-3 for the other set of crossbeams.
