Which lath includes backing?

Explanation:
Backed lath means the lath comes with a built-in backing material to give the plaster a solid surface to key to and to help hold the plaster in place. The designation on the lath that includes backing is the one with the RB suffix, which identifies a 3/8 inch lath that has this backing already incorporated. That’s why it’s the correct choice. The other options are standard plaster lath or metal lath materials that don’t include a built-in backing, so they don’t provide that reinforced backing surface.
