I have a V brace underneath my deck for stability, but I'd like to replace it with something that fits between joists. Im putting in an under deck ceiling and the V brace takes up some head room, so was hoping there were other ideas. I found some sway braces but my joists are about 11 inches apart, and the sway braces are 12 and 16 inch options.

Can I use wood 2x8's between joists, recreating the V formation? Seems like a lot of work putting in brackets on each board but if that would work I'd try it.

Any help appreciated.

  • Pictures will be better, but if it is what I think, you might be able to notch the joists so the braces are not in the way. Pictures will probably prove I do not know what I am talking about.

  • Why not throw some blocking between the joists?

  • Yeah I guess that's an option too, I just wanted to avoid having to add a bunch of brackets to keep the blocks in place. I've seen pictures where people just hold them in with 3 inch nails but that doesn't seem like it'll last that long. The flat tension bracing seems like a good alternative but here in the US they don't really sell the same stuff. Or at least not what Rohit posted.

These flat tension bracing are quite common in Australia and New Zealand.


It would be faster to install it too. Just nail it to the bottom of the joists (beams). You can get them in galvanized iron or stainless.

  • Interesting, so basically replace the 2x4's with the flat tension bracing in the same V pattern?

  • That is correct. It used to be used all the time for bracing walls, trusses, joists. Commented Jan 31, 2023 at 4:19
