I used to struggle with cabinet alignment for hours. With this clamp, I snapped a whole set together in half the time. It’s like having a second pair of hands!

The metric scale is a nice touch and the aluminum finish is top-tier. It hasn't rusted or jammed once in six months of heavy daily use in my shop.

The Woodworker's FAQ
What is the maximum thickness the clamp can hold?
The adjustable jaw is designed to accommodate most standard woodworking materials, comfortably handling thicknesses up to approximately 65-70mm, perfect for everything from picture frames to cabinet carcass construction.
Will the aluminum alloy rust over time?
Not on our watch! The clamp features a specialized surface treatment over the die-cast aluminum alloy, providing excellent resistance to corrosion and wear, even in humid workshop environments.
Can I use this for welding as well as woodworking?
While it's primarily a woodworking superstar, the aluminum construction is heat-resistant. However, for high-heat welding, we recommend our specialized steel clamps to avoid any surface damage to the specialized coating.
Is the measurement system in inches or millimeters?
This model is designed using the metric system, making it an ideal fit for precision-focused woodworkers who prefer standard metric workflows for their measurements.
