Stop if

Hold point on rtu curb height and rail alignment: I have the location, photo, drawing/detail, and what was checked. Who should verify before this gets cut, covered, lifted, sealed, energized, or signed off?

Watch out

Don't install generic curb without verifying RTU model. Don't skip flashing. Don't assume same rail spacing.
