Secure right-angle locking: Designed for fully sealed 90-degree joints, this quick-positioning clamp uses a unique screw-positioning mechanism to hold the clamp firmly in place. It locks on both sides for stable, accurate alignment during assembly or welding. Self-locking plate design: The self-locking plate removes the need for constant manual adjustments. Place the clamp, and it automatically aligns and locks, saving time and keeping both hands free for fastening or welding. Reliable and durable construction: Manufactured from new, robust materials for improved strength and lifespan. The reinforced design provides consistent performance for repeated use in workshop and jobsite environments. Easy to use and versatile compatibility: Works with standard right-angle and frame corners made from wood, metal, or composite materials. Ideal for a wide range of projects where precise 90-degree positioning is required. Key benefits — why you need it Ensures exact 90° alignment so joints meet squarely, reducing rework and improving final fit. Holds parts securely without constant clamping pressure, allowing faster, safer assembly and welding. Durable build means fewer replacements and dependable performance across multiple projects. Typical applications Woodworking: Assemble picture frames, cabinet corners, and furniture components with accurate, repeatable 90° joints. Metalworking and welding: Hold metal frame corners steady and square during tack welding or full welds to ensure straight, true assemblies. Home DIY and aquarium setups: Position and secure panels, frame corners, or mounting brackets where precise right-angle alignment is needed.
