Corner Clamps are hand-tools designed to hold two workpieces at a precise right-angle (usually 90°) during gluing, screwing or tack-welding, ensuring perfectly square joints without the need for manual bracing.
Key Characteristics:
-
Fixed-Angle Body: An L-shaped or triangular frame machined to exactly 90° (some models offer adjustable angles for mitres).
-
Adjustable Jaws: Sliding or screw-driven jaws accommodate varying material thicknesses, typically up to 50–75 mm.
-
Clamping Mechanism: Often a screw-drive or quick-release lever provides steady, even pressure at both faces.
-
Protective Pads: Removable plastic, rubber or nylon jaw pads prevent marring of delicate surfaces.
-
Durable Construction: Made from cast iron, steel or aluminium alloy, sometimes with corrosion-resistant finishes for workshop durability.
Common Uses:
-
Picture-Frame & Mirror-Frame Assembly: Holding mitred corners tight and square while glue or fasteners cure.
-
Cabinet & Box Construction: Aligning stile-and-rail or carcass corners at perfect right-angles before final fixing.
-
Small-Scale Welding & Fabrication: Positioning metal sections accurately for tack welding in jig fixtures.
-
DIY & Craft Projects: Ensuring precise corner joints in model-making, jewellery boxes or small furniture.
-
Repair Work: Re-squaring door or window frames when replacing or reinforcing corner joints.
