Which component is used for wood subfloor anchoring?

• A. Masonry Anchors
• B. Lag Screws
• C. Platform Gate
• D. Control Box

Answer: (B)

Anchoring into a wood subfloor relies on fasteners designed to grip wood fibers and pull the mounting surface tight. Lag screws fit that need perfectly: they have coarse wood threads and a thick shank that bite into the wood, letting you anchor a base plate securely to the underlying joist or blocking. This creates a strong, reliable hold for heavy equipment like escalator components. In contrast, masonry anchors are meant for concrete or brick and won’t perform properly in wood. Platform gate and control box aren’t fasteners for the subfloor; they’re other components of the system. So lag screws are the right choice for wood subfloor anchoring, with proper pilot holes and correct length to reach solid wood.
