Overview

The WEICHUAN 90 degree angle clamp is an aluminum alloy right angle clamp weighing 1.9 pounds, built to hold two pieces square while gluing, welding or fastening a corner joint.

Right angle clamps like this one solve a specific problem, holding two boards or metal pieces at a true 90 degrees without a third hand, which matters most for picture frames, boxes and small welding jigs. Aluminum alloy construction keeps the clamp itself light at 1.9 pounds without adding bulk to the workpiece.

  • Aluminum alloy right angle clamp
  • Holds a 90 degree corner
  • 1.9 pound weight
  • Suited to woodworking and light welding

Who it's for

Fits woodworkers, framers and light metalworkers who need a square corner held steady during glue up or tack welding. Not intended for clamping large, heavy panels where a bigger corner clamp or jig would hold more securely.

Pros and cons

Pros
  • Aluminum alloy keeps it light at 1.9 pounds
  • Holds true 90 degree corners for glue up or welding
  • Useful for frames, boxes and small jigs
Cons
  • Maximum clamping capacity not specified
  • Not built for large heavy panels

Performance notes

The clamp's job is to hold two pieces at a fixed 90 degrees while an adhesive sets or a weld is tacked, and its aluminum alloy body keeps it light enough to reposition often during a project. At 1.9 pounds it is easy to handle for small to mid sized joints, though the listing does not specify a maximum clamping capacity.
