The Clamp-King locksmiths’ cylinder vise is used with a small vise to hold lock cylinders for service. When the vise is tightened, the Clamp-King tightens onto the cylinder, holding with a vise grip that will not damage or deform any cylinder.

The milled sidebar pocket holds all GM 6 wafer plugs, with the sidebar extended. Reverse the tool to hold the sidebar retracted after picking. Holds firmly for removal and replacement of the tumbler spring retainer.

The Clamp-King also holds the most standard Key-in-Knob cylinders for service. Ideal for holding Medeco cylinders when installing or staking the spring retainers.
