YICYIO Square Corner Clamps – 4-Pack 6-Inch Right Angle Woodworking Squares for Cabinets, Drawers & Frames

Overview

Meet the YICYIO Square Corner Clamps, a practical 4-pack of 6-inch right-angle positioning squares designed to help woodworkers achieve clean, square joints. Ideal for frames, drawers, cabinets, and related assemblies, these clamps pair a simple design with steady performance to support precise alignment during glue-ups and fittings.

Constructed from engineering plastic, the clamps stay light yet durable enough for repeated use. The edges are slightly chamfered to reduce snags, helping protect both your hands and your project surfaces as you work. Their design also makes it easy to verify and refine right angles on wood, countertops, and other components, making setup faster and more repeatable.

How they work

Position the pieces into a perfect 90-degree arrangement, then tighten with the L-shaped metal screw and plastic nut to lock the joint. The system supports up to 1.5 inches (38 mm) of thickness, giving you flexibility with common cabinet and frame parts. The 6-inch square size (152 mm) provides a familiar reference for aligning corners at right angles.
