Buteline clamp tools are available in 4 sizes in the UK -- 10mm, 16mm, 22mm and 28mm.

There are the standard clamp tools in 16mm, 22mm & 28mm which are non-adjustable, the ProClamp Tools in 16mm & 22mm which are smaller but still robust tools ideal for use in restricted spaces, and the even more compact Mini Clamp Tool in 10mm.

A battery-operated clamp tool is also available, complete with charger and spare battery, with separate jaws in 16mm, 22mm and 28mm.
