Lưới Thoát Nước 5 Inch Cho Garage / Basement

I live in a crappy prefab house with questionable standards and history. I had a five inch cast iron grate shatter, and I couldn't find a replacement, so I made something that fit. I made the legs too long, but cut them to size with a garden shear. 

Since I have very little faith this is a standard size or that it's useful for anyone else, I haven't updated the legs and call this a cut to fit style design.

I have reinforced it to a reasonable degree, and I did step on it to seat it into the drain, but I wouldn't expect it to be load bearing.

Nominal size 5" diameter 3" height. Clearance is only around 25 thousandths, so make sure the grate size is 5 inch, not the opening diameter. 

The sum of the openings should be the same as the area of the 4" drain pipe beneath it, but increased friction would reduce the throughput. It's meant as a floor drain, not a service drain. 

I release this into the public domain in case anyone has any use for it.
