Drill 3 holes in the cap for screws (to attach the cap to the box.)
Place the drilled hole over the entrance to the box (with the open end of the cap facing out, so you can connect the tube), and attach it to the box with 3 screws. (Don't glue them together as then you will need a really long screwdriver, or one with an extension, to attach and remove the guard.)
