A corner clamp holds pieces at an angle during assembly. Some angle and miter clamps are made specifically for 90‑degree joints.

Typical work

  • Some corner clamps are intended for miter or butt joints. Check the joint types supported by the chosen clamp rather than assuming one design fits every joint.

Parts to compare

  • Some corner clamps have variable jaws and mounting holes for optional attachment to a work surface. These are model-dependent features.

Choosing capacity

  • When selecting a generic corner clamp, check the opening, depth of reach, and contact surfaces against the parts you intend to hold. The clamp’s general name alone does not reveal its specific capacity.

Holding limits

  • A generic corner clamp holds work temporarily. Do not use a clamp with a bent frame or spindle, and do not improvise extra tightening leverage with another tool.
