Vitavia Screwhooks twist-fit into the roof bar channels of Vitavia and Halls greenhouses. Pack of 10. The go-to fixing for stringing up tomatoes and training vine crops.
Thread each screwhook clockwise into the 25mm aluminium channel until the rubber washer sits firm against the bar. That washer prevents the hook from backing out under load. Each hook handles up to 5kg, which is enough for a single tomato stem tied to string running down from the roof.
For heavier loads or horizontal wire runs, space screwhooks every 60cm along the ridge bar and run 1.5mm galvanised wire between them. 12-month manufacturer warranty included.
