If you do construction layout, you know how frustrating it can be to decipher a set of working drawings that’s been soaked by rain or blown by the wind into a mud puddle. To avoid this problem, I protect the prints with the acrylic and plywood frame shown in the drawing. I make the frame a little larger than the job drawings, and I secure the pieces at the corners with machine screws and wing nuts. I figure the effort this frame takes is worth it, for someday it will probably save me a costly error caused by some faded-out dimension.
