Air-Powered Hold-Down Toggle Clamps


With Open Arm	With Solid Arm

Use for repetitive clamping and in production environments. Air from one inlet port engages the clamp, and air from the other inlet port disengages it. Clamps maintain the full-rated holding capacity even with a loss of air pressure. Fittings (not included) are required to connect the clamp's ports to a control valve and an air line.

With Open Arm—Clamps with open arm allow you to move the holding screw to any position along the arm. To achieve maximum holding capacity, position the screw closest to the base. Capacity decreases by as much as 65% when the screw is positioned at the end of the arm.

Air-Powered Push Toggle Clamps

Use for repetitive clamping and in production environments. These clamps secure when the plunger is fully extended to hold a workpiece from the side. Air from one inlet port engages the clamp, and air from the other inlet port disengages it. Clamps maintain the full-rated holding capacity even with a loss of air pressure. They have a threaded plunger to accommodate threaded holding screws and other threaded fixtures (not included). Fittings (not included) are required to connect the clamp's ports to a control valve and an air line.

Long-Life Dual-Mount Air-Powered Hold-Down Toggle Clamps

These clamps have double the service life of other air-powered toggle clamps. Use for repetitive clamping and in production environments. They have two sets of holes for mounting on the bottom or side. Air from one inlet port engages the clamp, and air from the other inlet port disengages it. Clamps maintain the full-rated holding capacity even with a loss of air pressure. Capacity decreases by as much as 65% when mounting at the end of the arm. Fittings (not included) are required to connect the clamp’s ports to a control valve and an air line.

Hydraulic Hold-Down Fixture Clamps


Clamping Arm Shown in Clamping Position (Sold Separately)	Clamping Arm Shown in Open Position (Sold Separately)	Hydraulic Ports

Best for CNC milling, these clamps combine 10 times the force of air-powered clamps with automated swing action for fast, secure workholding. Their clamping arm (sold separately) rotates up and out of the way when not engaged, so you can easily insert and remove your workpiece.

Connect your hydraulic line to the back or the bottom of the clamp. All ports are sealed with an O-ring and a screw; unseal the port you want to use.

Double Acting—Double-acting clamps use pressure both to clamp and release a workpiece, giving you precise control over the process. They’re more efficient than single-acting clamps, since their release is quicker and more predictable. They’re a good choice if you need to coordinate the action of multiple clamps.

Maximum Clamping Stroke—Maximum clamping stroke is the vertical distance a clamping arm can travel to clamp a workpiece.

Arms—Choose an arm best suited for your application. Machinable arms let you customize the length and shape to suit your application. Because they are longer than standard arms, you’ll have to use lower pressure, and their actual clamping force will be lower than the listed rating.
