In need of a bracket to hold to 22.5° miters together?

I have about a three inch gap between the top of my kitchen cabinets and the ceiling. So I'm making soffits out of cover panels that match the doors to essentially extend the cabinet box to the ceiling. In one corner, there's a cabinet that faces out at a 45 degree angle. I've got the cover panels cut to the correct length and mitered at 22.5°, but I'm running into an issue with keeping the mitered edges together. This is especially true at the top (near the ceiling), which tends to lean back with the weight of the footboard that the cover panels are attached to. I don't think I could easily glue the two miters together because: (a) I don't know of any way to keep them clamped together, and (b) one side is about 6 feet long, the 45° corner is 16 inches, and the other side is about 9 inches - I doubt that I could transport that into place without the glued seams breaking. My thought is that if I could get some 135° brackets to put along the backside of the panels where the miters meet, that would solve the issue. But I haven't come across many places that sell this specific product (which makes me think I'm going in the wrong direction). Could I achieve the same thing with pipe hanger straps or something similar? Any advice is appreciated. submitted by /u/Red__Burrito [link] [comments]
