Keeps joints square and hands free — a precision corner clamp that holds work at a true 90° while speeding assembly and reducing rework. Key benefits Accurate 90° positioning: Engineered to maintain a stable right-angle so frames, boxes, and joints align correctly the first time, reducing gaps and errors caused by shifting parts. Secure, single-hand operation: Built-in pressure-lock mechanism and non-slip contact surfaces prevent slippage and let you set and hold pieces with one hand, lowering the need for constant readjustment. Smooth, low-effort use: Spring-assisted opening provides consistent, easy clamping action for faster repetitive work and less hand fatigue during longer projects. Versatile compatibility: Adjustable to fit varying material thicknesses, making it useful across a wide range of woodworking and furniture assembly tasks. Reliable construction and performance: Sturdy design keeps components stable throughout glue-up and fastening so joints remain square while you work. How it solves common problems Stops parts from moving during glue-ups or screw installation, eliminating misaligned corners and wasted time. Replaces the need for temporary supports or extra hands when positioning and fastening frames, cabinets, or trim. Reduces hand strain and saves time with repeatable clamping action and secure pressure-lock holding. Practical applications Picture frames and shadow boxes: Hold mitered corners at a precise 90° while you glue or staple. Cabinet and drawer assembly: Keep carcass corners square during fastening to ensure proper fit and function. General woodworking and furniture projects: Align joints for gluing, nailing, or drilling across a variety of panel and frame thicknesses.
