Step 3
Attach the inner rails to the sides of the chassis:
a) Remove the inner rails from the slide rail assemblies.
b) Align an inner rail with each side of the chassis:
• (2110/2120) Install three 8-32 x 0.25-inch Phillips screws into each side of the chassis, and align the inner rail
so that the three slots on the rail line up with the screws on the chassis.

• (2130/2140) Align the inner rail so that the three slots on the rail line up with the three pegs on the side of the
chassis.

c) Set the keyed slots over the screws/pegs, and then slide the rail toward the front to lock it in place on the screw/pegs.
The rear key slot has a metal clip that locks over the screw/peg.
d) Using one M3 x 6-mm Phillips screw, secure the inner rail to the side of the chassis to prevent sliding.
e) Install the second inner rail to the opposite side of the chassis and secure with the other M3 x 6-mm screw.
