This is a new set of T-compression devices designed for precise fixture, alignment, and clamping of workpieces. It includes a T-shaped slide limiter, a woodworking position limiter, and wood clamp fixing and tensioning tools. Key benefits - Precise workpiece installation and positioning for repeatable results - T-shaped slide limiter supports accurate alignment and stable clamping - Wood clamp fixing and tensioning tools provide reliable clamping force - Simple structure enables quick setup and easy operation - Wide range of applications in wood and metalworking What it does - Enables accurate positioning and secure fixation of parts during assembly, routing, drilling, or other machining tasks - Acts as a dependable jig component for fixture setups and tensioning in multi-piece assemblies Applications and use scenarios - Woodworking: install and position boards in a jig for routing, drilling, or joinery, using the T-shaped limiter to establish reference alignment and the clamps to fix parts firmly - Woodworking/jig work: set up components for precise drilling or sanding operations, with reliable tensioning to prevent movement - Metalworking: fixture workpieces for drilling, tapping, or welding, ensuring stable alignment and consistent clamping force through the T-compression system Notes - Suitable for workpiece installation and positioning in many wood- and metalworking applications - Specific sizes and materials are not listed; designed for compatibility with standard jigs and fixtures in woodworking and metalworking environments
