Air-Powered Hold-Down Toggle Clamps
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.
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.

Dual-Mount Air-Powered Hold-Down Toggle Clamps
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.

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.

Auto-Adjusting Low-Profile Hold-Down Toggle Clamps
Hold workpieces of different thicknesses with one clamp. These clamps automatically adjust to compensate for variations in size. The handle secures in a horizontal position for more clearance above the clamp than standard hold-down toggle clamps. They have an open arm, so you can move the holding screw to any position along the arm. The holding capacity stays the same regardless of the holding screw's position. The screw has a nonmarring tip.

Auto-Adjusting Heavy Duty Hold-Down Toggle Clamps
Hold workpieces of slightly different thicknesses with one clamp. These clamps automatically adjust to compensate for imperfections or small inconsistencies on the material’s surface. A highly durable construction with hardened steel pivot pins provides a long service life. Use the clamping arm to hold your workpiece, or drill and tap a hole to add a threaded holding screw (not included).
