No..this is not a commercial. I looked everywhere for one of these Woodpecker Squares a couple of years ago. I got lucky and found a used one. It's been one of my most used tools both for set up of my Festool table and for checking squareness on scraps. Since I already own the 26", I'm going for the 18". Compared to a friends 24" Starrett, my WP shows no lite along the edges. Just wanted to let you guys know...no affiliation.
Now, for that 6' Starrett straight edge...
