The SB-2 is an upgraded version of our SB-1 machine.
Here is whats included
1. The upper arm now has cut outs to allow compound bends for +45 degrees, 90 degrees, -45 degrees. This allows for more complex cage building possibilities. the lower arm matches the upper arm.
2. leveling tool to keep your bends parallel, I have found this to be a major help on my builds.
