The IRWIN® Vise-Grip® Locking C Clamp (18DR) is designed for professionals and DIYers needing secure, extended clamping for tasks like welding, auto body repair, and sheet metal work. Its key benefit is an exceptional 190mm (7.1/2in) jaw capacity and a deep throat that allows access to difficult-to-reach areas. A potential caveat is its specialized nature, making it less suited for everyday light-duty clamping needs.

The clamp has a maximum capacity of 190mm (7.1/2 inches). This refers to the maximum width of material the jaws can grip when fully closed.
The throat depth of this clamp is 250mm (10 inches), allowing it to secure materials further from the edge.
A hex key (Allen wrench) is required for fine adjustment and release using the adjusting screw.
While the hex key allows for precise adjustment, the primary design is for robust clamping. Use caution and adjust pressure carefully for delicate materials.
The overall length of the clamp is 455mm (18 inches).
Yes, it can be used for woodworking, especially for larger projects or when a deep reach is needed, but it is primarily designed for metalworking applications.
Position the jaws correctly on the workpiece and use the hex key adjusting screw to tighten until a firm, secure grip is achieved. The locking mechanism will hold this pressure.
Ensure the hex key adjusting screw is tightened sufficiently. Check for debris or damage on the locking mechanism or jaw surfaces.
Clean the adjustment screw threads and apply a light lubricant like WD-40 or machine oil. Ensure the screw is aligned correctly with its guide.
Ensure the hex key adjusting screw is fully loosened. The maximum opening is determined by the clamp's design; verify if the workpiece exceeds the maximum capacity.
Clean the affected area with a wire brush and apply a rust inhibitor or lubricant. Store the clamp in a dry place to prevent future corrosion.
Setup: This clamp is ready to use out of the box. To operate, open the jaws by squeezing the locking levers. Position the clamp onto the workpiece, ensuring the jaws are fully engaged. To tighten, use the hex key adjusting screw located at the end of the handle to draw the jaws firmly against the material. For release, use the same hex key to loosen the screw until the jaws disengage.
Compatibility: The clamp is designed for general-purpose clamping of various materials including metal, wood, and plastic. Its effectiveness depends on the user's ability to position the jaws correctly around the object needing to be held.
Care: To maintain performance, keep the jaw surfaces and adjustment screw clean and free from debris. Apply a light coat of oil to the adjustment screw threads periodically to ensure smooth operation. Store the clamp in a dry environment to prevent rust. Regularly inspect the locking mechanism and jaw tips for any signs of wear or damage.
