Deco, huh. When I was researching what I wanted to use, I saw "Deck-O-Drains". Those I saw were one-piece, channel + grate, cut-to-fit units. I went with a commercial unit and the grates are only 2' long but are 4" wide. I have 15 grates. If one should break, it is easy to replace. These grates are so thick and heavy, I cannot imagine breaking one, but just in case I dropped a heavy clay pot on one, or some other mishap occurred, I wanted to be covered. I put the channel drain in for two reasons. I can literally wash down the entire room with a hose if I want to. Since I will have two large windows and a screened door, and they will be open on nice days/nights, if it should rain and "flood" into the room, the drain will easily carry the volume of water out into the yard.
