Review on TEKTON 8 Inch Sheet Metal Clamp/ Bender Tool - 3855 by Robbie Guinn

Flat surfaces have ridges around them as if cut in a press. I had to file these tabs to avoid damaging the aluminum I was shaping. Also remember that when clamping, the flat surfaces do not lay flat on the raised surface. They are angled towards small objects. The clamp did all the work for me, but it was a simple 30-second sheet aluminum bend project. Not 5 stars because of the tabs on the clips.
