Bottom ledge can be extended to right to accommodate up to 76" canvases

Middle ledge can be adjusted left or right over the 72" length.
You can lock in, for example, a 48" canvas
and a 18" x24" piece of plywood to serve as a
table top for paint, brushes etc.

With the mast horizontal you can pick up the left end and roll the easel where ever you want with ease.
