I’m building a dining nook. I’ve got a good plan in mind, but one thing is causing me some consternation. See the pictures below: I’m unsure how to fasten the TOP of the support brackets to the wall. I could use very long lag bolts and face screw it, but that wont look nice. I could also use an angled lag from the top (as drawn), or I could?????
Is there some sort of bracket anybody has used that would work well in this situation? It needs to be strong, as this is a bench. And the top point will have the most load. The fastener on the bottom will have much less load. I’m thinking a smaller screw that I can easily plug.

I’ve thought of using some sort of keyhole type hangers, but I dont know of any beefy enough…

Perhaps sneak a french cleat into the back

I thought of French cleats, but I’m just not sure how to work them in this situation. There’s only 1.5” of bearing for each bracket, and I dont know if a fr. cleat would withstand that kind of load…

I schemed up another plan. Think itll work? I’ll have to buy some angle iron and do a little metal fab…

Have you checked out some of the various bed rail cleats? Some are recessed and completely hidden.

Why not build the french cleats into your bench, basically replacing the brackets?

You could basically build an apron under the bench itself, in between the brackets, and make it a french cleat. You could use screws through the horizontal brackets into the end grain of the cleats and down through the seat. Then you can plug the holes to make them kinda disappear.

Use a ledger board. Notch your brackets around a 2×3 and screw through from the back of the ledger into the brackets. Then lag screw the ledger to the wall into studs. Then apply the seat board and screw down into the ledger before applying the back.

Thanks for the tips!
