I have a client who wants us to construct a fence like the one below. Simple enough. But there are three things I can't figure out just based on this photo. 1) What size are those 3 boards going horizontal? Do you think those are 2"x4"s or 1"x4"s? 2) What do you think it looks like on the opposite side? If those are 1"x4"s then I would guess it looks the same on the other side. But if those are 2"x4"s then there wouldn't be enough room on the other side for any vertical boards. Right? 3) Does it look like there is a thin cap on top? It looks to me like there is a really thin 1"x4" cap or something like that. I'll attach the regular photo as well as an altered one that I blew up a little in Photoshop..... . .
