Screw these clamps directly into a tapped hole and use air pressure to quickly and consistently clamp and release parts when welding. Compact and lightweight, these clamps are easy to move and reposition when welding. They’re also known as swing clamps. Connect these clamps to a control valve and air line. When pressure is applied, the arm on these clamps rotates 90° into position over your workpiece before clamping down. When pressure is released, the arm rises and rotates out of the way, so you can load or unload parts.

Replacement Arms—Replacement arms (sold separately) do not include a holding screw. Extended arms (sold separately) give your clamp a longer reach than standard arms. However, you’ll have to use lower pressure, which means the actual clamping force will be lower than the clamp’s listed rating.

Arm Adapters—Add an arm adapter to mount your own custom-machined arm.

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.

Compact and lightweight, these clamps are easy to move and reposition when welding. Adjust the air pressure to quickly and consistently clamp or release parts. When pressure is applied, the arm on these clamps rotates 90° into position over your workpiece before clamping down. When pressure is released, the arm rises and rotates out of the way, so you can load or unload parts. They’re also known as swing clamps. Attach a sensor (not included) to activate relays and controllers. Connect their ports to a control valve and an air line. Use screws (not included) to mount the base to a flat surface.

All clamps come with a holding screw.

Arm Adapters—Add an arm adapter to mount your own custom-machined arm.

Two sets of holes allow mounting on the bottom or side. Use these clamps 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. They have an open arm, so you can 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. Fittings (not included) are required to connect the clamp’s ports to a control valve and an air line.

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.

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.

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.
