Micro™ Expanding Machinable Clamps
Jergens Micro™ Expanding Machinable Clamps are available with extra material on the clamping jaw so they can be machined to conform to the shape of your workpiece - enabling you to fixture unusual applications easily. The specially designed steel wedge spreads the clamping force uniformly on both sides of the aluminum channel. A unique locking plate is provided to make the clamp rigid while machining the jaw to your specifications, without vibration.
