About this task
The rails are labeled left and right, and cannot be interchanged. The front side of each rail is labeled Left Front or Right Front

the cabinet.
NOTE: Install the left rail assembly first.
2. Fully extend the rear sliding bracket of the rail.
3. Position the rail end piece labeled
Left Front facing inward and orient the rear end piece to align with the holes on the rear
cabinet flanges.
