Compatible with vacuum annealed and galvanized wires specified above. Typical applications Vineyard and orchard tying: secure branches and vines quickly during pruning and training operations where repeated ties are required. Nursery and landscaping: bundle stems, stakes, and plant supports with consistent tightness without damaging delicate material. Light packaging and construction: fast securement of cable bundles, piping protectors, or component packs where a durable wire tie is preferred. How it solves common problems Reduces manual fatigue by automating repetitive tying tasks and delivering a consistent knot in under a second. Adapts to different bundle sizes through a broad diameter range and tenstep tightness control to avoid overcompression or loose ties. Minimizes downtime with a capacity battery that recharges quickly and supports thousands of knots per charge. Included control features Tenlevel tightness adjustment to match different materials and applications. Switch lock for added safety to prevent accidental operation during transport or storage. Model KOWY450 provides a balanced solution for users needing a fast, portable, and precise wire tying tool with durable wire compatibility and reliable battery performance.
