I'm building a saddlebag type of kayak rack on my dock walkway where the load-bearing cross beam travels under the walkway (vs on top as saddlebag implies).
The walkway stringers are comprised of two side-by-side 2x8s that run the length of the walkway, one on each side. I am trying to figure out what kind of mounting bracket I can use to hang my 2x6 crossbeam underneath that can be mounted (hung) on the double 2x8s.
There are some truss framing brackets, but all I could find were the type you nail in. I would rather run a carriage bolt through to ensure integrity.
