Engineered Trellising for Professional Grape Vine Trellis

VIT-S is a professional-grade solution for building a trellis for grape vines, designed specifically for commercial fruit growing and viticulture. 

This wire trellising product allows fast tool-free installation directly onto wooden or metal end posts, replacing outdated methods like chains, clamps, and turnbuckles. As plants grow, wires can be adjusted independently, which makes it an ideal tensioned wire trellis system where pruning and harvesting efficiency are essential.  

With support for wire diameters from 1.40 mm to 2.60 mm and a load rating of 880 lbs, the Vit-S guarantees durability and precision. Whether you’re constructing a vineyard trellising layout or refining an existing grape vine trellis, the Vit-S, along with the optional bracket and integrated hook deliver optimal flexibility across all post types.
