Back in the day (7 years ago) the business I worked for needed an extra large support table for a "v-nailer". The table needed to be at a 45 degree angle an large enough to assemble 96" long picture frames. Becace of the size of the table, the boss (owner) wanted the top of the table attached to the wall for a strong support. This is what I came up with:

I ripped a 2x4 in half and beveled at 45 degrees. Worked like charm, in seven years it hasn't moved at all.

Nice job, I'm surprised it didn't sag a little in the center. That photo shows it being quite straight. Well done!

Cool solution!!

ooh la la.....it's French!!! oui!!!!

When I installed this I drilled 3, 4" deck screws through the table and both halves of the French cleat. The table is "stretched" into position and held in place with tension. Again, I took these pictures today and I built this 7 or 8 years ago. Kinda proud that it's still in use and looking good, several of the other things I built are doing as well. One device I made is used to stack pallets of art on a pallet to prepare for shipping. After I retired they built another half dozen of them, they are based on the plans for a doorstop, just expanded to a cinderblock for the weight.
