(Fully-support the lower section of the leg while removing). Figure 3.4.
2. Choose a height and align the corresponding set of leg holes.
3. Install the (4) previously removed screws in the new holes and tighten securely.
4. Repeat this procedure on the second leg. Make sure to use the same set of
holes as used on the rst leg.

1. Carefully stand the desk upright-this will require at least two people.
2. Attach the chair rail with (2) 1/4-20 x 2” FHM screws as shown. Figure 4.1, 4.2.
The chair rail should extend above the worksurface, and the countersunk holes
should be on the outside.
3. Tighten all screws securely.
Note: If you are assembling a 60 or 72” desk, attach the center of the
chair rail to the chair rail bracket using the 3rd at head screw.
(The chair rail bracket may require slight adjustment to align properly.)
