1. Specifications: This is a new product for greenhouse accessories - Windproof Slot, which serves to secure greenhouse film, netting, and shading net. It requires connecting plates for assembly.

2. Groove Depth: Approximately 11mm deep, it can accommodate both film, mesh, and shade net simultaneously, or directly hold double springs. The structure of this product's groove is different from that of a standard card slot, providing a tighter and more secure fit than ordinary slots, reducing slippage (the spring is less likely to pop out), excellent wind resistance, and the film is less likely to be blown away.

3. Slot Width: Approximately 30mm, about 2mm wider than a standard card slot.

4. Available lengths include 4 meters and 6 meters, with other sizes available upon request.

5. Material: Hot-dipped galvanized steel plate cut and pressed, zinc coating meets the industry standards for greenhouse construction, designed for normal use of about 5 years.
