Found this truus in a brand new home, the angled web in two places was not secured under the nail plate…
How does a builder fix this problem?
Good pick up Tim;
Another item of Quality Control that slipped and left the Plant.

Great catch I would guess 2 L shaped pieces of Plate do not know if it would be approved but should do the job . Marcel?

The last time that happen to me the Manufacturer sent a sketch that indicated to install a 3/4" plywood both sides, nailed and glued. Typical of any remedial repairs that may be required. Truss Manufactures can come up with off the wall repairs.
Those little plates must have a lot more strength then we can imagine.

Totally agree, Those are typical repairs that I see all the time.
I also see the homeowner repair of hammering them back when they bent or replaced…which is WRONG! They need to be pressed.
Try tearing a truss apart if you want to get a feel for how well gangnails hold. They hold!
