Threaded Air-Powered Hold-Down Fixture Clamps
Screw these clamps directly into a tapped hole and use air pressure to quickly and consistently clamp and release parts. The arm rotates 90° into position over the workpiece and then moves straight down to clamp. Disengage to rotate the arm out of the way and load or unload parts. Also known as swing clamps, they're used with a solid state switch or Reed function switch with M8 male 3-pin connectors. Connect the clamp's ports to a control valve and an air line. To hold clamps in an untapped hole, use a mounting block (sold separately).
Clamps with rubber-tipped holding screw are nonmarring. Tip is removable.

Air-Powered Hold-Down Fixture Clamps
Adjust the air pressure to quickly and consistently clamp and release parts. The arm on these clamps rotates 90° into position over the workpiece and then moves straight down to clamp. Disengage to rotate the arm out of the way and load or unload parts. Also known as swing clamps, they are used with a solid state switch or Reed function switch with M8 male 3-pin connectors. Connect the clamp's ports to a control valve and an air line. Clamps mount with screws.

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.

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.

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.
