Lay out the two side rails on a soft, flat surface. Note which side rail is right and which is left. The attached steel shelf-mounting brackets should all face inward on both rails.
Start with the right side rail and attach the largest shelf (19" deep) to the first steel bracket mounted just above the leg. Make sure cut-outs on shelf are facing toward the back. Insert screws into underside of shelf bracket and then up into the pre-drilled holes on the right side of the shelf. Tighten using a Phillips screwdriver (Figure 1).
Continue adding progressively smaller shelves to the right side until all five are attached with the smallest shelf on top (Figure 2).
Repeat steps 2 and 3 with the left side rail (Figure 3).
Turn unit over so shelf cut-outs are facing up (Figure 4).
Attach the wire management panel vertically into shelf cut-outs using sharp, self-drilling screws (Figure 5). Make sure top of wire management panel is flush with third shelf from bottom (A). Tighten screws with Phillips screwdriver.
Place a plastic bumper in each corner on the back of every shelf. In addition, place two bumpers on the top back of each side rail pole for extra wall protection.
Tip unit upright next to the wall, moving the unit slightly so the top of frame, or top shelf, touches the wall first (Figure 6).
For safety, secure the desk to the wall with the drywall bracket. Find an appropriate location along a back edge of one of the top shelves; it does not need to be centered. Anchoring to a wall stud is best, but if you cannot find a stud, a drywall anchor will work as well.
