Brand new, open box. I ordered the wrong model. For this to work, the blade of the skill saw has to be on the right side of the saw. They call that a right handed saw. I'm right handed and hold my saw with my right. I can see the blade on the left side of my saw, so that's a left hand skill saw. I'm selling this for $150. I paid $165 plus tax and shipping.
This is a right hand saw model and should work on most battery saws. Will not work on an electric worm drive. That's is another model and comes with larger diameter mounting bolts.
