I designed my drafting board around the Para-liner Parallel Straightedge 30". I wanted a more portable drafting board then my previous table models. The installation was easy. The adjustments for lining the para-liner was easy.

Checked the flatness of my board and yet my instruments slide under the parallel. Is there an adjustment for this?

Best Parallel Line for the money anywhere!

Very good product, seems to be high-quality, it is replacing a mainliner that I’ve had for over 30 years quality and design seem to be the same. I look for this one last also

The deetailed instructions were easy enough to follow, but they did require close attention. It feels tight. So far, so good.
