5. Measure the rail distance from the inside of the front mount bracket to inside of the back mount bracket to
determine if it matches the distance between rack posts.

6. If the distance does not match, relocate the rear mount bracket to within an inch of the post-to-post depth distance
you recorded and align the rear mount bracket holes to the demarked holes on the outer rail. For example, if you
recorded 27.5 inches, you would use the 27- and 28-inch holes marked on the rails.

7. Insert and tighten each setscrew with a #2 Phillips-head screwdriver to a torque of 12 lbf-in (1.36 N-m), then perform
a fit check to validate the correct rail length.
8. Repeat the process for the right outer rail, using the proper orientation for the rack cabinet and rail.
9. Turn over the right outer rail assembly to access the inner side of the rear outer rail, then locate the CMA B bracket
attachment holes.
IMPORTANT Orient the rail with the bracket front to your right, the rounded rear of the bracket to your left,
and the outer rail away from you.
10. Select the CMA B bracket from the CMA box.
