Adjusting the Length of the Left Front Rail
Adjusting the length of the left rail at the rear of the cabinet.
Slide the rail flange over the face of the rear cabinet rail (see inset).
Note: The rails are pre-configured to adjust to cabinet rail depths of between 26.18 in. (664.97mm) and 28.93 in. (734.82mm). For cabinet rail depths outside of this range, remove and reposition the four rail adjustment screws (illustration below ) to support your required rail length.
