What placement is required for metal wall ties in relation to walls?

1. At every stud

2. Every 24 inches

3. Every 12 inches

4. At the top of each wall

The correct answer is: Every 24 inches

The requirement for the placement of metal wall ties in relation to walls is that they should be installed every 24 inches. This is a key aspect to ensure proper structural support and stability of the wall assembly. The placement every two feet helps to tie the outer wall to the inner wall, which is critical for maintaining the integrity of the wall and providing resistance against lateral forces, such as wind or seismic activity. Using metal wall ties at this specified interval effectively distributes the load and prevents the outer veneer from separating or bowing, which could lead to structural failures. It contributes to the overall durability of the wall system, ensuring that the outer covering, such as brick or stone, is securely anchored to the frame of the building.
