A heavy-storage shelf uses ordinary screws into gypsum board alone, with no framing engagement or load-rated anchor arrangement. What should be provided?

Correct Answer

D) A verified load-appropriate backing, framing or approved anchor/support arrangement.

Use a support and fastening arrangement suitable for the shelf system, wall construction and intended load. Approved anchor systems can be valid; unsupported screws into gypsum alone do not establish capacity. Source: https://www.rubbermaidpro.com/media/cyhftgdy/fg11z800_wire_install_guide.pdf

Answer Options

D
A verified load-appropriate backing, framing or approved anchor/support arrangement.
