SPLASH GUARD-Back and 2 ends for a 18" shelf -NO screws/washers (only supplied if shelf purchased at same time)
This guard and two ends can be fitted inside the cage around the shelf. To fit this way is a little more difficult, and would require 2 people.
The easier way to fit is externally and is simply offered externally behind the shelf and screwed into it.
There are various holes to choose screw positions.
The back and 2 ends will hold in position if the tab on the ends is slid into the rolled top of the back piece
