Plug vises that are adaptable for plugs from .480″ diameter to .550″. These vises can be hand held or secured in a bench vise. Only two vises are needed. Plugs, when loaded, will rotate in vises in the same manner as in the cylinder shell. Vise can be adjusted to any tension. The key blank will not drop below the radius of the plug so that the shear line can be maintained. High pins will show up when the plug is rotated. Made from solid steel for durability with the usual Framon precision.
