inner rail will read "R" for the right or "L" for the left embossed on the side that faces away from
the chassis. Right and Left are with reference to looking at the front of the enclosure.
a. Orient the inner rails so that the flat side is facing the enclosure and the side with the
grooves is facing away from the enclosure.
b. Align the keyholes on the inner rail to the mounting pegs on the side of the enclosure
and press the inner rail flush against the chassis. If the keyholes don't line up with the
pegs, flip the rail length-wise to see if this will align them.

c. Slide the inner rail toward the rear of the chassis to lock it in place. There will be an
