61512 - Piher Maxi R-120 Heavy Duty Reversible Piston Clamp 48-Inch

The Ultimate Clamp for Welding Environments

For professional welders, equipment durability is non-negotiable. The Piher Maxi R-120 Reversible Piston Clamp (48-inch) is specifically engineered to thrive in the harsh conditions of a welding shop. The critical advantage of this clamp lies in its fully encapsulated double-threaded piston system. Because the screw mechanism is completely enclosed within the housing, it is impervious to welding spatter, metal shavings, and grinding dust. This protection ensures that the clamp will never seize up or become damaged by hot slag, a common failure point in exposed-thread clamps.

Fabrication often requires more than just holding parts together; fit-up and alignment frequently demand spreading force. The Maxi R-120 features a reversible jaw design that allows you to switch from clamping to spreading in seconds, without the need for extra tools. This is invaluable for squaring up frames or pushing warped steel into alignment before tacking. With a massive 10,000 N of force at your disposal, you can manipulate heavy steel sections with confidence. The 12 cm (4.7-inch) throat depth provides ample reach for clamping around flanges or box sections.

Ergonomics and safety are also prioritized. The handle is articulated, allowing you to apply maximum torque comfortably and then fold the handle out of the way to clear the work zone or prevent accidental bumps. The moving jaw features a non-slip brake that holds the clamp in place on the bar before pressure is applied, making vertical setups much easier to manage single-handedly. Built with a heavy-duty 40x10mm steel bar, this Piher clamp is a long-term investment in efficiency and reliability for any serious fabricator.
