NRH 3101-180 Heavy Duty Toggle Clamp | SPCC Blue Zinc Plated Quick Release Clamp
Made to Order
The NRH 3101-180 is a professional-grade Heavy Duty Toggle Clamp engineered for rapid and secure fastening in demanding industrial applications. Featuring a robust SPCC steel construction and a durable Blue Zinc Plating finish, this clamp delivers exceptional strength with reliable corrosion resistance. Its standout feature is a precise screw adjustment mechanism, allowing the working length to be fine-tuned between 166.5mm and 187.5mm to accommodate various workpiece thicknesses. With an impressive clamping force of 2743N (280kg) and a user-friendly quick-release blue handle, it is designed for efficient, repetitive use where speed and holding power are critical.
Primary Applications
This versatile toggle clamp is ideal for quickly securing workpieces across numerous sectors:
-
Metal Fabrication & Welding: Holding parts in place for welding jigs, fixtures, and fabrication tables.
-
Woodworking & Carpentry: Securing boards for cutting, sanding, gluing, and assembly in shop fixtures.
-
General Assembly & Manufacturing: Used in production jigs, assembly lines, and inspection stations for part positioning.
-
DIY & Workshop Projects: A reliable tool for hobbyists and makers needing strong, adjustable clamping.
How It Works (Operating Principle)
This clamp operates on a powerful over-center toggle mechanism. The blue handle acts as a lever. Pushing it down engages the clamping arm, which moves through an over-center point to lock securely, applying the full 2743N force to the workpiece. The adjustable screw allows for precise setting of the clamping arm's reach. Pulling the handle up quickly releases the tension and retracts the arm, enabling fast loading and unloading of materials.
