When I purchased my Waterbox tank I also purchased a Red Sea Customizable DIY Aquarium Net Cover. I bought the 60" x 31" kit to fit the inside of my tank (60" x 26" outside footprint) and to accommodate the center rectangular overflow.
First let me say that knowing what I know now about the fragility of the screen material I would probably search for a more robust solution but since it is in place and is performing well I guess serious complaints now are a bit academic. What I don't like now, however, is the inconvenience of the cover in terms of removal and replacement on a large tank. In addition to the overflow I needed to build in cutouts for two Ehiem automatic feeders that are on the end walls. Of course I have a large light that is supported on brackets that also rest on the ends.
Removal of the screen cover without removing the light and the auto feeders is precarious at best and, although I have done it, I do tend to hold my breath a little during the process. Usually during water changes I remove the lights and the feeders and then the screen and this has resulted, in more than one occasion, in one of my Giant Danios jumping to the floor. It each occasion the event was brought to my attention by one of my cats. Luckily I was able to retrieve the fish each time before his interest evolved beyond curiosity. This needs to change and I have purchased another kit (the smallest) with the intent to rebuild the cover in 3 sections.
The intent is to break down the existing screen; cut the long front frame piece to make two pieces that match the length of the two rear frame pieces that extend from the rear corners to the outer edges of the overflow; and build end sections that will cover the the top from the end walls to the outside edges of the overflow. I will then build a center section that will use the inner frame section of the end covers for support.

This isn't a good pic of the current cover and I plan to take a better one tonight when I get home.
EDIT: Here ya go. A little distorted. I had to go to wide angle on the phone to get it all in.
