Tired of Having to Design & Build Your Locking Clamps!?

The Quadloc® pneumatic rotary swing arm clamp is an all-in-one standard locking unit that stays locked with the loss of air pressure.

This compact swivel cylinder clamp with a strong mechanical lock, makes for an easy fit into any design with a straightforward installation and minimal design costs.

The independent rack and pinion rotate allows for more flexibility and less chance of design interference compared to a standard pneumatic, swivel swing clamp. No need to worry about clockwise or counter-clockwise clamping.

Internal Mechanism

Our Patented Quadloc® Technology Eliminates the Need for Seperate Rods Locks

True mechanical wedge lock with no stored energy.

Our 4422 and 4425 Quadloc® swing clamp models produce clamping forces of up to 400lbs.

The holding force will always be 500lbs regardless of clamping force.
