I am building an open porch with the roof supported by 8inch fiberglass columns. Porch measures approximately 12 x 21 ft. I am trying to source some type of uplift protection that I can fish through the hollow columns to secure the porch roof to the foundation. I usually use Simpson products, but can’t find anything in their catalog. Am I missing it or is there another supplier of a product that will work for me? Thank you.

Look at Simpson shear wall anchors if you are going over a poure slab our concrete piers. You have to buy the correct length all thread rod I believe (been awhile sinse I used them).
If it is over a wooden structure I might be incline to use just all thread square plates over/under both top and bottom beams.
Postive attachment
Is there room inside the column for a post and if so u can attach the roof using simpson hangers. .I also used steel cable to rap around upper and lower framing members..
I'd probably go with steel aircraft cable.
Can ya run a 4x4 up through the hollow columns? That might allow the use of some existing hardware.
