I cannot seem to find the right bracket to use as a hold down on the tree side for a treehouse knee brace beam. I need to find one that can bolted to the tree and hold two 2x8's. It looks just like this but I can't find it anywhere.

enter image description here

Also, how do you attach the knee braces to the corners of the platform? There seems to be various ways of doing that. Thanks!

Not too hard -- the page I suspect you got that photo calls it a "hold-down bracket," and that exact part appears to be available here, fastenersplus.com

the bracket

I'll take my finder's fee in chocolate :-)

  • WOW, I have looked up and down for this! Where do I send the chocolate!!! I assume 2.5 inches wide will hold two 2x8's? THANK YOU!!!

  • 2-1/2" won't be great for 2-2x8, as you'd have to remove 1/2" of material (thus weakening the support). Better would be 2 brackets with slices of 1/2" ply padding out the 2x material. Commented Aug 31, 2016 at 2:37
