Here's a picture of a used drafting table. EngineerSupply does not sell any used products at all ever, but this photo of a used one I am using to explain how parallel straightedges and drafting tables work together. I
thought someone might want to see the Parallel Straightedge that’s mounted
on this one. This is a very WIDE drafting table and the straightedge the person bought isn’t same width but it works as you can see in the photo. Also, at the bottom edge
there's a Spiroll drawing protector, which is a product we used to sell before Spiroll went
out of business years ago. Named the "Spiroliner" made by Spiroll was an aluminum tube that had a slit in the
topside and drawings would roll up inside the tube so you could work on the top
of large drawings without having to lean over, and also your belly wouldn’t press
or crease the drawing if it was hanging off the edge of the desk. Anyway,
little education of drafting tables, parallel straightedges, and spiroll
drawing protectors.
