Location: 06 Wood & Plastic : Structure.
TrusJoist has updated their product line. The TJI model numbers which end in '50' are being phased out. You should stop using them immediately. You should modify the structure plans of any current project not under construction.
I have updated the objects which contain TJI specs with the new model data. The old numbers are still available, but they are moved aside with a reminder to not use them.
