Professional Adjustable Triangle - Inking Edge

I'm really enjoying my products. They work well and are high quality.

I gotta be honest, this is the first adjustable triangle I’ve ever used. I purchased it because I’m currently working on drawings for a friend of mine house. His roof pitch is pretty drastic and I got tired of constantly having to keep adjusting me 30/60 or 45/90 triangles to get the right angle. After adjusting it and tightening up the thumb screw it worked absolutely awesome. Took the guess work out of the equation and I was able to keep all of my lines uniformly. I luv this piece of equipment and I highly encourage anyone who are drawing really out there angles to invest in one.
