I was taught that it is a scaffold, but I recently discovered that the scaffold has an extra turn.
I joined the "swivel on my bridge" club today. I'll be checking out how it feels tomorrow. I just never could justify the cost.
I went for the larger DMM so that I can fit the gate of my rhino through it when it's all loaded with wrench stuff. I think it may be a bit heavy to have swinging around in that area.
