These are the ones I use. You're using twice as many vs the other ones but there is zero need for basement access. They work very well. Fasten Master has something similar now that I would like to try.
But that will cost more than the $200 they want to pay :laughing:
Dang Mike, you only charge $30/hr? :jester:
Or just 2 blocks of 2 x ma material and a string.It would be interesting to see what it looks like to put a long straight edge right under the ledger along the wall there. If it was built that way I'd bet there is a big bump there. If the deck rim joist is straight I think it's safe to assume it was.
