Frequently asked questions
What should I measure before buying corner clamps?
Measure stock thickness/width, required reach or opening, and the bench, track or miter-slot interface. Compatibility is often the first filter.
Is higher clamping force always better?
No. Alignment, jaw geometry, reach and controlled pressure can matter more, especially on finished wood or delicate assemblies.
How many do I need?
Buy for the assemblies you repeat. Glue-ups often need several matching clamps, while a specialty jig or vise may only be needed once per station.
