Hi, I'm new to the forum. I have 15 feet of Simpson Dura Vent un insulated double wall sitting on top of two Simpson Dura Vent 45s. Long story why it has to be done this way. Any way, I think it's a lot of stress on those 45s and am looking for a decorative bracket that would bolt to the masonry behind the pipe and clamp/screw to the outer wall of the pipe above the 45s to take some of the load. I saw a wrought iron one years ago but can't find one now. Any one know where I can get one or have other suggestions? Thanks in advance.
