Crop bars are the secret of true versatility in a Polytunnel. Made of galvanised steel, they are fixed across the hoops at head height and can be used suspending wires, canes or hanging baskets. Crop bars also help to strengthen the structure, providing extra protection against heavy winds on particularly exposed sites.
