What flat material is used to mount the chart? Plexiglass, white tile board, foam core, gatorboard? What are the dimensions of your test chart?
We use gatorboard for the ones we move around, white board for the permanent ones. The smallest charts are 40" diameter, the larger 60" the largest we have is 74" but with wide angle lenses I wish I had some even larger.
