For woodworkers who want square joints without a third hand
A set of four 5.5" aluminum alloy corner clamps that hold two pieces at a true 90 degrees for frames, drawers, cabinets and furniture.
😩 The Everyday Struggle
Gluing up a corner is a juggling act. Boards slide, angles drift, and a joint that looked square on the bench ends up slightly off once the glue sets.
✅ These clamps lock two pieces at a precise 90 degrees, so your corners stay square while the glue sets.
Key Benefits

📐 Holds a true right angle
CNC-processed for precision, each clamp keeps your pieces at 90 degrees. Use them for gluing, splicing and welding wood pieces without guessing at the angle.

🛡️ Aluminum alloy build
Made from durable aluminum alloy, these clamps are built for repeated use in the shop. The CNC-processed design is made for long-lasting use.

🔴 Red anodized finish
The anodized finish resists rust and corrosion. It also makes the clamps easy to spot on a busy workbench.

🖐️ Chamfered edges, easy handling
Slightly chamfered edges help prevent scratches on your hands and on the woodwork. A metal L-shaped screw and plastic nut secure the wood in place.
Who It Is For
If you build or repair anything with square corners, this set fits right in. Four clamps let you hold several corners at once.
- 🖼️ Picture frames Hold each mitered or butted corner at 90 degrees while the glue sets, so the frame closes up square.
- 🗄️ Drawers and cabinets Keep box corners true during assembly. Clamp boards up to 3.5 inches thick.
- 🪑 Furniture projects Line up legs, rails and panels at a right angle for gluing and splicing.
