PFD Series Pneumatic Frame Clamps

Series PFD Pneumatic Frame Clamp is engineered to deliver consistent, high clamping force across a wide pressure range, making it ideal for demanding body-in-white, frame welding, and heavy fabrication applications. Its rugged cam-driven mechanism generates up to 4,581 lb (20.4 kN) of total clamp force, ensuring reliable part retention even on large or complex assemblies.

Designed for flexibility, the PFD features wide jaw throat openings, multiple jaw styles, and robust tooling surfaces with dowel pin locations to simplify fixture design.
