How It Works

• Quadloc® clamps are intended for continuous air pressure, but if air pressure is lost, it will stay clamped/locked with the same holding forces. The Quadloc® clamp was designed for this power down (loss of air) situation.

• The only way the unit will unclamp is by energizing the unclamp/release port.

• The unit clamps when air pressure actuates the piston, driving the wedges under the carriage and raising the main shaft up (refer to the 3D function animated video above).

• The cam arms prevent the wedges from backing out, which locks the shaft in position. This is why the Quadloc® clamp can attain such high holding forces. 

•Holding force for our 4422 and 4425 models will always be 500lbs regardless of clamping force.

• Quadloc® clamps lock at any desired position on the 5.8mm stroke.


• The swing arm accessory, #22-11, has a flexible, 360° orientation.

• Quadloc® clamps have an independent rotate which can be actuated in either clockwise or counter-clockwise rotation.

• The rotate is designed so that flow controls are not required. A minimum of 40 psi is required to operate the independent rack and pinion rotate.
