Ok so this is fun. We are finally redoing our deck on our house that was built in the 70's.

The stair treads were these nice wide low-angle kind, using a bracket made by Erecto-pat, which is no longer in business at all! I find it baffling that NO ONE makes a stair step bracket like this, at least nowhere that I can find! Literally the only thing I could find on the entire internet is this ebay listing:

If anyone knows a similar part, that would be super helpful. Otherwise I am going to have to go to a custom metal fab shop to get some made!

Side note, their patent expired, so if you wanna make some bucks, start making some of these up! They work perfectly for stairs. The only reason I need new ones is some are rusted after all these years.
