Black heavy-duty outdoor netting is made from UV protected mesh that is 1.5 mm (0.16 inch) thick. Made in USA, opaque look netting is more than 7 times thicker than standard deck netting. Cannot be torn by hand: can be cut with scissors. Guaranteed against sun rot for 3 years. Black cable ties (38) included for installation. Each mesh "rectangle" measures 1/2 inch. Barely visible from a distance. Child proofing is easier with Kids Edge products from Cardinal Gates. NOTE: Please check your netting regularly to ensure product performance. There is NO substitute for adult supervision of a child.
