Mo-Clamp: The Original Self-Tightening Clamp

When professional body technicians need to pull damaged metal back into spec, they reach for a name that has defined the collision repair industry for decades. Mo-Clamp, manufactured by Pull-It Corporation out of Oregon, is widely credited as the originator of the self-tightening clamp — a design built around a patented wedge pulling ring that delivers an increasingly firm grip the harder you pull. That single innovation changed the way body shops approach structural repair, and it remains the cornerstone of the brand's identity today.

Modern vehicles are engineered with increasingly complex frame geometries, mixed-metal construction, and tighter tolerances than ever before. Mo-Clamp has kept pace with those changes by continuously expanding its product catalog to meet the demands of real shop environments. Today the lineup spans everything from specialty hooks and draw bars to anchoring systems, measuring gauges, and pulling accessories — giving technicians a single trusted source for the tools that matter most when precision counts.

Lifting, Pulling, and Gripping — Built for Every Situation

The breadth of Mo-Clamp's catalog reflects the variety of challenges that show up in a busy body shop. At the core of the lineup are Lifting and Pulling Clamps, the product family that made Mo-Clamp famous. These clamps are constructed from heat-treated alloy steel and engineered to handle multi-ton pulls without slipping. Whether you're dealing with a pinch weld, a sill, a frame rail, or an awkward corner, there is a Mo-Clamp clamp designed for the exact geometry you face.

For jobs that don't fit neatly into a single-purpose tool, the Multi Purpose Clamps in Mo-Clamp's catalog provide the adaptability shops need. These versatile tools bridge the gap between specialty clamps, letting technicians tackle pulls from multiple angles or across different panel types without swapping out entire setups.

Mo-Clamp's Hook and Loop Kits round out the anchoring and attachment side of the equation. Hooks in various profiles — J-hooks, sill hooks, handy hooks, and more — connect seamlessly with chains and pulling systems, giving technicians flexible attachment options for virtually any repair scenario. The kits are designed to work within Mo-Clamp's broader ecosystem, so components stay compatible across different jobs.

Frame Straightening and Power Pulling Systems

For structural work, Mo-Clamp's Frame Straightening Machines and related equipment bring the same precision engineering philosophy to bench and rack systems. Down pull assemblies, pulley blocks, and adapter plates integrate with pulling towers to allow straight, angled, and horizontal pulls — giving technicians the control they need to restore factory dimensions on modern unibody and full-frame vehicles alike.

Rounding out the heavy-pulling side of the catalog, Mo-Clamp's Power Pullers offer high-capacity pulling force for the most demanding repair jobs. These tools are built to the same heat-treated steel standards as the rest of the Mo-Clamp lineup, ensuring that high-force operations remain controlled and safe from start to finish.

Why Professionals Trust Mo-Clamp

What sets Mo-Clamp apart is not just the breadth of its catalog but the consistency of its engineering. Every tool in the lineup is built to integrate with the others, creating a cohesive, adaptable system rather than a collection of unrelated tools. For collision repair professionals who work on a wide range of vehicle makes and models, that interoperability is invaluable — it means a shop can invest in Mo-Clamp tools incrementally and always have components that work together.
