To install MAAS bi-directionally on concrete, how many anchor plates are required?

• A. Two
• B. Three
• C. Four
• D. One

Answer: (B)

Stability under bi-directional loads comes from using three anchor points. Placing anchor plates in a triangle fixes the plate’s orientation in the plane and prevents rotation, so the load can be transferred in any direction without the base tipping. Two anchors would allow rotation about the line between them when off-axis forces occur, while four anchors add redundancy and distribute load more evenly but are not required for basic bi-directional stability. Therefore, three anchor plates are needed.
