A vise or clamp for rigidly supporting and holding tanks, such as containers for compressed and liquefied gases such as refrigerant gases, fuel gases, and the like, while their valve assemblies are removed and installed. The vise is of simple sturdy construction permitting easy placement and removal of the gas container. At the same time, the gas container is held securely against rotation to permit relative rotation of the valve assembly. The vise is made in a variety of sizes to accommodate gas containers of different sizes. The vise may be used either horizontally or vertically. |
