I need to replace the railings that were on my front porch (made of cement). I plan to use PT wood in a balluster design. However, I'm at a loss as to how to secure the posts to the porch without the brackets showing. The only thing I can think to use are angle brackets but I don't want them showing. Nobody seems to make a bracket that the posts can slide into and then hide unless I go with aluminum but the cost is prohibitive. Does anyone have any ideas on how I can tackle this problem? Is there someone out there that makes a product that will do what I want that I just haven't found yet?
