Secure and Understand Seam Setter Functionality

What happens here

The user places two specialized seam setter tools onto the granite countertop, straddling the seam. These tools feature white blocks with vacuum suction cups and metal rods connecting them. The first tool is shown engaging its suction cups to firmly attach to the countertop. The presenter then explains that these tools use vacuum pumps to secure them, ensuring the countertop pieces are held tightly together. He highlights that one side of the tool has a mechanism (a crank or lever) to pull the two countertop pieces together horizontally, closing the seam tightly. The other side has adjustable cams for vertically leveling the two pieces, making the surface perfectly flush. He mentions using two such tools for larger seams, allowing for more precise control over the seam's alignment.

Goal: Securely position seam setters and comprehend their role in achieving a perfect seam.
