For over 35 years, we've served our valued, worldwide customers by providing clamps that are built to suit a wide variety of industrial and OEM applications. Whether you need a clamp to push, pull, hold down, lock, position, or tighten, we'll either help you find exactly what you need from our standard off-the-shelf clamps, or we'll custom-build a clamp to perfectly suit your application.
All die-stamped steel parts are deburred, cleaned, and zinc-plated for a finish that resists corrosion and creates a smooth, easy to clean surface.
Toggle mechanism designed to allow maximum clearance for ease of loading and unloading workpieces.
Our clamps with unique features:
Higher Base (Greater clearance)
Side Mounting (Saves fixture space)
Yokes (Clamp 2 parts with 1 stroke)
Long U-Bolts (Extend the reach of Latch Clamps)
Reverse Action (Lowers the profile of Push Pull clamps)
Hand grips are covered with
an oil and stain resistent red
vinyl or red plastic for easy
identification and to assure
the safety and comfort of the
Heavy duty rivets are used to maintain accuracy and to increase endurance. All heavy-duty clamps receive hardened ground pins and bushings.
The theoretical maximum holding of clamping force of a toggle action device is achieved
when the three pivot points are in a straight line. To make allowance for external forces due
to vibration and changing load conditions in industrial use, the proper amount of over
travel of the center pivot point has been carefully calculated to yield maximum clamping
pressure, while achieving a positive locking position.
Holding Capacity and Clamping Force
All GOOD HAND™ clamps are rated by their "holding capacity." This rating is the maximum force the clamp will
support when locked in the closed position without creating permanent deformation. This force is measured at a
point closest to the base and diminishes as the end of the bar is reached. The "clamping force" is defined as the
actual force being applied by the clamp to the workpiece. This rating is not constant due to such variables as the
location of force on the handle, the amount of force the operator applies, and the location of the spindle on the
