What amount of wiggle is allowed on a grab bar?

• A. None
• B. A small amount
• C. A moderate amount
• D. Any amount

Answer: (A)

Grabs bars in accessible spaces must be firmly secured to solid backing so they don’t move when someone relies on them for support. Any wiggle indicates the mounting isn’t adequate—hardware, backing, or anchor points may be insufficient, which can lead to the bar pulling free or shifting during use and a fall.

In practice, inspectors test by applying force to the end of the bar to feel for movement. There should be no detectable wobble or play; even a small amount means the installation isn’t safe. That’s why the correct answer is none—zero movement is required for a grab bar to be considered properly installed and safe.
