Is there a MNFR for special connectors other than Simpson Strong Tie? We have some weird connections and we like to avoid designing and fabricating special hangers & connectors.
If you need any concealed, more custom hardware,
try Timberlok for jointery type connections. Very affordable.
You just have to bite the bullet for the expensive jig for precise hole drilling.
I worked as a truss engineer for a manufacturer and would occasionally need a specialty hanger fabricated. I found USP to be the better choice over Simpson. They have engineers that will design a hanger to fit your need using a finite element package and provide you a signed and sealed calculation with a capacity.
