Need some help locating...

[Salty]

....a particular piece of metal.
I need to support a section of subfloor that is about 18" long.
It is 3/4" particle board and I had to cut it back past the floor joist to get into the solid part. It had gotten wet. Now I have a section that has no support under it and I cannot go to the next floor joist because that us under the tub. I also cannot get to the area from underneath.
I know I saw, or maybe had at one time, a piece of metal that was offset by the thickness of the metal. I'm thinking that this would be a way to put a support under that section. Fitting it under the subfloor and then fastening the other side to the top of the floor joist. The cut back is right next to the joist, like the picture below.
Anyone know where to get such a piece of fmetal?
TIA, Salty

Your hardware store may have a simpson strong tie catalog that you can page through and perhaps find something that does that or can be cut to do that.

Good luck.

Couldn't you just sister another joist alongside the existing one? (Or have you nailed the subfloor down already?)

Nothing there to nail the subfloor to. If I cut back far enough to put a 'sister' joist in then that cut will have no support. The area was repaired at some time in the past due to a leak around the toilet. And that is what I am doing as well. The area I'm dealing with is just about a 10" wide area between the toilet and the tub. It is a mobile home and there is no easy way to get to the underside.
After tinking about this, maybe I could just use a flat plate and cut the top of the joist down about 3/32" or the thickness of the plate.
I think I'll do that.
Thanks all for your help.
