Flat rib lath must weigh how many pounds per square yard in the listed options?

Explanation:
Weight per area of lath is a basic spec used to match plaster systems. For flat rib lath, the standard published weight per square yard is 2.75 pounds. This lighter weight reflects the rib design and gauge chosen to provide a good key for plaster while keeping handling and overall weight manageable. The other options correspond to heavier lath configurations or gauges (such as raised ribs or thicker metal), which is why they’re not the correct specification for flat rib lath.
