Why Choose the Bivarlo 90 Degree Right Angle Clamp?

Corner clamps vs right angle squares — what’s the difference?

Standard corner clamps apply pressure from one direction. Positioning squares — like this 90 degree right angle clamp — register against two faces simultaneously, ensuring both the clamping hold and the 90-degree angle are maintained in a single setup. This makes them particularly effective for glue-ups where precision matters most.

Reliability and Durability

Built to last with high-quality aluminum alloy that maintains its performance and integrity over time, even with regular use. A tool you buy once and rely on for years.

FAQ

Frequently Asked Questions

What is a 90 degree right angle clamp used for?
A 90 degree right angle clamp — also called a positioning square or corner clamp — holds two workpieces at a precise right angle while glue sets or fasteners are driven. It’s used in woodworking, welding, framing, and cabinet making to guarantee square corner joints without manual measuring during assembly.
What’s the difference between a corner clamp and a positioning square?
A corner clamp typically grips two pieces and applies pressure toward the joint. A positioning square registers against both faces of the workpiece to guarantee a true 90-degree angle while holding them in place. The Bivarlo 90 degree right angle clamp combines both functions — it positions and holds simultaneously.
Can I use this for welding as well as woodworking?
Yes. The aluminum alloy body is rated for both woodworking and metal fabrication. Many welders use 90 degree right angle clamps to tack-weld square frames before final welding. If clamping bare metal, place a scrap piece between the jaw and workpiece to prevent marring.
Why do I need two clamps in the set?
Using two clamps lets you hold opposite corners of a frame or box simultaneously — critical for keeping the assembly square while glue cures. With only one clamp you’d have to assemble corner by corner, which risks the earlier joints shifting before everything is locked in.
What size material does the 7.1 inch clamp accommodate?
The 7.1-inch jaw works with a wide range of material thicknesses common in woodworking and metalwork — from thin plywood and drawer panels up to thick hardwood boards and steel sections. It’s sized for the majority of typical shop and fabrication work.
