Great solution to my 100 yr old 1st floor deflection issues. Numerous MEP obstacles made sistering the old joists inefficient. A bit of drilling/screwing but well worth it.
It is a good product. Well made pre-drilled and structural screws with it. Price was ok little high than I was hoping but I understand testing and all that. I will shop here again if I run into this situation again. Thank you
