MFT Bench clamps clearance

[HowardM]

Hi,
I have decided to make myself a MFT Workbench, based on a PaulK worktop box type of construction.
I am using the space below the top to collect sawdust/shavings so they are easily vacuumed out.
I have found conflicting information on this question.
Can someone say with confidence, what the minimum clearance is needed for clamps etc underneath a MFT Top.?

Thx
Howard

2 inches for this kind of clamp.
