What are the maximum centers on which metal lath strips must be installed?

• A. 6 inches
• B. 9 inches
• C. 12 inches
• D. 15 inches

Answer: (C)

The requirement for installing metal lath strips specifies that they should be fastened at a maximum of 16 inches on center. However, most standard practices and codes often require installation at 12 inches on center to ensure stability and durability, especially in applications like stucco or plaster systems. This approach helps prevent cracking and allows for a more uniform application of the finish coat. Choosing 12 inches aligns with industry standards, providing adequate support for the finishing materials and enhancing the overall integrity of a wall system. Therefore, it ensures that the lath strips will effectively carry the weight and stress applied to them, creating a reliable substrate for subsequent layers.
