Position the left and right rail end pieces labeled FRONT facing inward and orient each end piece to seat in the holes on the front side of the vertical rack flanges.
Align each end piece in the bottom and top holes of the desired U spaces.
Engage the back end of the rail until it fully seats on the vertical rack flange and the latch clicks into place. Repeat these steps to position and seat the front end piece on the vertical rack flange.
To remove the rails, pull the latch release button on the end piece midpoint and unseat each rail.
