Diylog 90 Degree Corner Clamp 4-Pack 5.5" Aluminum Right-Angle Squares, Red Anodized, Holds 3.5"

The Diylog 90 Degree Corner Clamp 4-pack are aluminum right-angle positioning squares that hold boards securely at 90° while you glue, screw, or assemble frames, cabinets, drawers and other woodworking projects.

These compact L-shaped clamps are machined from anodized aluminum and sized for versatility: each 5.5" (140 mm) square accepts stock up to 3.5" (90 mm) thick and includes threaded fastening hardware and a plastic storage box. Built for repeatable squaring, the set removes the guesswork from joining corners so pieces stay aligned during glue-up, nailing or assembly.

How do these clamps make frame and box assembly faster?

By locking two workpieces at a precise right angle, the clamps free both your hands for adhesive application or fastening. Their rigid aluminum bodies resist flex so corners remain true while you finish the joint.

• Hold picture frames, drawers, small cabinets and boxes square during glue-up
• Accepts board thickness up to 3.5" (90 mm)
• Quickly aligns corners for nailing, screwing or stapling

What features ensure accuracy and durability?

The Diylog clamps are CNC-machined from aluminum and given a red anodized finish to resist corrosion and wear. Slightly chamfered edges protect both your workpiece and your hands, while precise mating faces deliver consistent 90° geometry.

• CNC precision machining for true right angles
• Corrosion-resistant red anodized surface
• Rounded edges to prevent marring or injury

How easy are they to use and fasten?

Place the clamp on the inside or outside corner, insert the L-shaped metal screw and plastic nut, then tighten to secure both boards. The simple hardware lets you reposition the clamp quickly for repeat setups or multi-corner projects.

• Simple L-screw and plastic nut tightening mechanism
• Works from either side of a corner for flexibility
• Compact size speeds multiple clamping operations

What projects are these best suited for?

These clamps shine on small-to-medium woodworking builds where true corners matter. They’re ideal for hobbyists and pros assembling frames, furniture components, cabinets, birdhouses and mailboxes or for checking squareness on countertops and saw cuts.

• Picture frames, shadow boxes and decorative frames
• Drawer boxes, cabinet carcasses and small furniture assemblies
• Alignment checks for countertops, miters and square cuts

Who is this for? The Diylog 90 Degree Corner Clamp set is made for do-it-yourselfers, woodworking hobbyists and tradespeople who need a compact, repeatable way to hold corners square during glue-ups and fastening. If you assemble picture frames, small cabinets or boxes and want a durable, easy-to-use tool that speeds assembly and improves joint precision, this four-pack supplies multiple fixtures for simultaneous clamping and tidy storage in the included plastic case.
