A buddy and I are developing a product that drops into a drain and does, well, stuff. We designed it for our tub drains which are about 1.25 inches deep from the lip at the top of the drain, down to the cross-member support, then 1.5 inch diamter across the top of the drain.

However, it does not seem that there is any standardizaiton of these features (only the outside pipe thread diameter is standardized). So my question, before my buddy and I start milling these things in my basement, is: 1) is 1.25 inch depth the norm, 2) do most drains contain this cross member support, 3)are most tub drains 1.5 to 1.375 inches inside diameter, and 4)are most drain inserts steel with nickle or chrome coating that may flake off (friction of our device on the inside drain surface could potentially flake off a drain surface that isn't really solid)?

I know this is a lot to ask, but I can't seem to get these questions answered elsewhere, and these are the primary questions preventing me from getting my little device into older homes...where I think its needed!
