Jones & Shipman Engineers Rack Vice 82mm jaw width, 45mm jaw opening, 65mm heigh & 145mm base width so approx 120mm fixings Afraid I don't know a lot about the item so hopefully the pictures inform you. It belongs to a friend who's husband used to have an engineering workshop. Please see my other items for more engineering parts. All I know is they don't make things of this quality any more!
