During the chalk test, if the door is not centered from top to bottom, what is the likely cause?

• A. Warped gasket
• B. Ballistic doors
• C. Loose hinge
• D. Misaligned strike plate

Answer: (B)

During the chalk test, a door that isn’t centered from top to bottom points to how the door sits in its frame and how it’s mounted. Ballistic doors are heavier and built with tighter tolerances and special framing to handle high-security requirements. If such a door isn’t aligned perfectly, it can sit off-center because the frame, hinges, or shims weren’t matched to the door’s weight and geometry. The chalk test will reveal this misalignment as the door binding or contacting the frame unevenly along the top and bottom edges. In contrast, issues like a warped gasket, a loose hinge, or a misaligned strike plate usually show up as sealing gaps, hinge looseness, or latch misfit rather than a consistent vertical off-center position across the height of the door. So, a not-centered condition in this test most plausibly points to the ballistic door’s installation and alignment characteristics.
