Step 4
Install the slide rails into the rack:
a) Align one slide-rail assembly front end with the front rack-post holes that you want to use.
The slide rail front-end wraps around the outside of the rack post and the mounting pegs enter the rack-post holes
from the outside-front.
The rack post must be between the mounting pegs and the open securing
plate.
Note
b) Push the mounting pegs into the rack-post holes from the outside-front.
c) Press the securing plate release button marked 'PUSH.' The spring-loaded securing plate closes to lock the pegs in
place.
d) Adjust the slide-rail length, and then push the rear mounting pegs into the corresponding rear rack-post holes. The
slide rail must be level front-to-rear.
The rear mounting pegs enter the rear rack-post holes from the inside of the rack post.
e) Attach the second slide-rail assembly to the opposite side of the rack. Make sure that the two slide-rail assemblies
are at the same height with each other and are level front-to-back.
f) Pull the inner slide rails on each assembly out toward the rack front until they hit the internal stops and lock in place.
