The STT hooks are used for irrigation systems in orchards and vineyards for holding the polyethylene tube on a guide iron wire.
With a single movement the tube can be attached to the supporting wire, without leaving any space between the two in order to avoid the growing of tree shoots in between. Thanks to a notch carved in the hook the tube is tightly attached to the wire preventing any detachment. The easy and fast installation procedure makes the STT hook the preferred choice of the installers.
