This procedure is for installation in the topmost position in the rack unit. (See the
illustration on the following page.)
1. If you have two top drawer guides to install, at the rear of the rack put nut clips
in the 2nd and 3rd holes from the top on both sides. Then from the rear of the
rack, install the two top drawer guides (the dimples on the front of the guide fit
into the 1st and 3rd holes at the front).
If you do not have two top drawer guides to install, at the front of the rack, install
one nut clip in the 2nd hole from the top on both sides.
2. At the rear of the rack install nut clips in the 15th and 17th holes from the top on
each side of the rack.
3. From the rear of the rack, insert the two pins of the rail into the 20 and 22nd
holes from the top at the front of the rack. On each side attach the rail to the
15th, 17th, 20th, and 22nd holes from the top at the rear of the rack, using four
M5x14 hex head screws.
