18. Gather the replacement rails and prepare to install them.
19. Remove the inner rail that is nested inside the rack rails.
Note: There are Right and Left rails and they must be installed as a set. Each
inner rail will read "R" for the right or "L" for the left embossed on the inside.
Each outer rail will read "R-Front" for the right or "L-Front" for the left. Right and
Left refer to when you are facing the front of the rack.
a. Start by sliding the inner rail out of the outer/rack rail until the safety latch engages and
the inner rail will not extend further. It will only slide one way.
b. Press on the safety latch release spring located on the side of the rail and slide the
inner rail out the rest of the way.
