Setting blocks are essential components used in window and glass installation. They are small, firm pieces (usually made of rubber or plastic) that help position and support glass properly within a frame or window system. Think of them as cushions that keep the glass from directly touching the frame while ensuring it stays level and secure. Glaziers use these blocks to make sure windows are installed correctly and safely, preventing glass from cracking due to pressure points or improper weight distribution. You might also hear them called "glazing blocks," "glass setting blocks," or "window setting blocks" in job descriptions and resumes.
