This is an OEM replacement lid for the DrainBox. We have drilled out the 2 holes and supply 2 brass screws.
Installation suggestions:
1) Put a mark on a screw at about the 1/2 way point
2) Screw only 1 screw into the Replacement DrainBox Lid
3) Place a piece of tape on the opposite side of the screwed in side that will adhere to the bottom, around the side and up so that it makes a handel to hold onto
4) Hold onto make shift handel and slide screw into the hole in the DrainBox
5) Use handle to stablise the opposite side so that you are able to insert second screw into the hole.
6) Tighten second screw so that the head is flush with the outside of the box. (screwing it in too far might and the screw will not be resting in the correct position)
